The winter months often bring a change in our routines. Shorter days and colder temperatures can make it tempting to stay indoors and scale back on physical activity. However, this season presents a unique opportunity to focus on building strength and muscle. But how do you structure your training when the environment itself feels like a challenge?
This guide provides a structured, science-backed approach to your winter workout. We’ll explore how your body adapts to training in the cold, what the research says about building muscle during this season, and provide you with actionable workout plans. You’ll learn not just what to do, but why it works, empowering you to train effectively and safely all winter long.
Is It Good to Work Out in Winter?
Exercising during the winter is not only good, it can also be highly beneficial for both your physical and mental health (1). While the cold requires some adjustments, your body is fully capable of performing and adapting.
From a physiological standpoint, your body has mechanisms to maintain its core temperature, allowing you to train safely in colder conditions (2). Furthermore, maintaining a consistent fitness routine through the winter helps counteract the seasonal tendencies toward a more sedentary lifestyle, which can lead to weight gain and a decline in cardiovascular health (1).
Mentally, exercise is a powerful tool against the winter blues, or more formally, seasonal affective disorder (SAD) (3). Physical activity releases endorphins, which are natural mood elevators (4). A consistent winter workout routine can improve mood, reduce stress, and boost energy levels, which helps you feel your best even when the days are short (3).
Can You Build Muscle in Winter?
Absolutely. The fundamental principles of muscle hypertrophy – the process of increasing muscle size – remain the same regardless of the season.
Muscle growth is stimulated by creating mechanical tension, metabolic stress, and muscle damage through resistance training. As long as you provide your muscles with the right stimulus and support them with adequate nutrition and recovery, you can build muscle effectively during the winter (5).
Interestingly, research provides some unique insights into the body’s processes during this season:
Vitamin D’s Role
A 2019 study published in Current Developments in Nutrition highlighted a fascinating mechanism your body uses in winter. Vitamin D levels naturally fall due to less sun exposure (6).
However, the study found that skeletal muscle acts as a functional storage site for the main form of vitamin D measured in the blood, which helps support overall vitamin D levels (6).
As vitamin D is essential for muscle function, this storage system is vital for supporting your winter training efforts.

Energy Demands
Training in the cold increases your body’s energy expenditure. A study examining Norwegian soldiers during winter military operations, published in Applied Physiology, Nutrition, and Metabolism, found that energy expenditure was significantly elevated. Soldiers engaging in a demanding ski march expended an average of 3,369 to 5,717 calories per day (7).
This high metabolic demand underscores the importance of nutrition. To build muscle, you need to be in a caloric surplus or at least at maintenance (8). The increased energy burn in winter means you must be extra diligent about consuming enough calories and protein to support muscle protein synthesis (9).
While winter presents factors such as lower vitamin D and higher energy needs, these are variables you can manage. With a well-designed program and a solid nutrition plan, you can make significant muscle gains during the colder months.
For those who prefer to avoid the cold altogether, there are numerous ways to structure an effective workout at home. Find out more about indoor exercise.
What Are the Best Exercises for the Winter Season?
The best exercises for winter are those that are aligned with your muscle-building goals and can be performed consistently, whether you’re at a gym or at home. As the primary discussion of this article is hypertrophy, the focus should be on progressive resistance training. Compound and isolation movements are both valuable.
Compound Exercises: These are multi-joint movements that work several muscle groups at once. They are highly efficient for building overall strength and mass (10). Examples include squats, deadlifts, bench presses, and overhead presses.
Isolation Exercises: These are single-joint movements that target a specific muscle. They are excellent for adding volume and ensuring all muscles are adequately stimulated (11). Examples include bicep curls, tricep extensions, and leg curls.
A comprehensive winter workout plan will include a mix of both. The colder weather does not fundamentally change which exercises are effective, but it may influence where you perform them. If you’re training outdoors, a dynamic warm-up is even more important to prepare your muscles and joints for the load (12).
A 2017 meta-analysis in the Journal of Strength and Conditioning Research provides powerful insights into how to structure your sets. The study compared muscle growth and strength gains between high-load (lifting heavier weights for fewer reps) and low-load (lifting lighter weights for more reps) training, with all sets taken to momentary muscular failure (13).
The key finding for hypertrophy was that muscle growth was similar across a wide spectrum of loading ranges. Whether participants trained with heavy loads (above 60% of their one-rep max) or light loads (60% or below), they achieved comparable increases in muscle size, averaging between 7.0% and 8.3% growth (13).
What does this mean for your winter workout? You have flexibility. You can build muscle effectively using heavy weights, moderate weights, or even lighter weights, as long as you train with a high level of effort and push your sets close to failure (13).
This is particularly useful for a winter workout at home, where you might not have access to heavy equipment.
The best winter workout plan is one that you can stick to consistently. It should be structured around the core principles of progressive overload, volume, and recovery. Below are two sample 4-day workout splits: one for the gym and one for home.
These plans incorporate a mix of loading ranges to stimulate hypertrophy through multiple pathways.

Proper form is essential for maximizing results and preventing injury (14). Below, you’ll find step-by-step instructions for every exercise that’s featured in the gym-based and at-home winter workout plans. Follow each movement closely, focusing on both technique and control.
Barbell Bench Press
Lie flat on a bench with your feet planted firmly on the floor.
Grip the barbell so your hands are slightly wider than shoulder-width apart.
Unrack the bar and position it above your sternum with your arms locked.
Inhale, then lower the bar slowly to touch your mid-chest, keeping your elbows at a 45-degree angle.
Press the bar upward until your arms are fully extended, exhaling as you complete the rep.
Bent Over Rows
Stand with your feet hip-width apart, barbell in hands with an overhand grip.
Hinge from your hips until your torso is nearly parallel to the floor, letting the bar hang at arm’s length.
Engage your core and drive your elbows behind you, pulling the bar toward your lower ribs.
Squeeze your shoulder blades together at the top.
Lower the bar back to the starting position in a controlled manner.
Incline Dumbbell Press
Set the bench to a 30-45-degree angle and sit with a dumbbell in each hand, resting on your thighs.
Lie back, bringing the dumbbells to shoulder height with your palms facing forward.
Press the weights upward, locking out your arms overhead.
Lower the dumbbells under control to the starting position, elbows at about a 45-degree angle.
Lat Pulldowns
Sit at the lat pulldown machine, adjusting the thigh pad tightly against your thighs.
Grasp the bar with a wide, overhand grip.
Pull the bar down toward your upper chest, driving your elbows down and back.
Pause at the bottom, feeling your lats contract, then return the bar slowly to the top.
Dumbbell Lateral Raises
Stand tall with a dumbbell in each hand, your arms at your sides.
With a slight bend in your elbows, raise the dumbbells outward to shoulder height.
Hold for a second, then lower with control back to your sides.
Tricep Pushdowns
Stand at a cable station fitted with a straight or angled bar attached high.
Grip the bar with your palms facing down and your elbows tucked at your sides.
Push the bar straight down until your arms are fully extended.
Return the bar up slowly until elbows are at 90 degrees.
Dumbbell Bicep Curls
Stand upright with a dumbbell in each hand, your arms extended and your palms facing forward.
Keeping your elbows close to your torso, curl the dumbbells up toward your shoulders.
Squeeze your biceps at the top, then lower slowly to the starting position.
Barbell Squats
Step under the bar, positioning it on your upper back (traps), and grasp it with both hands.
Take a step back, set your feet shoulder-width apart, and make sure your toes are turned slightly out.
Brace your core and squat down by bending your hips and knees, keeping your chest up.
Lower until your thighs are at least parallel to the ground.
Push through your feet to stand back up, keeping your back straight.
Romanian Deadlifts (RDLs)
Stand holding a barbell or dumbbells at thigh height, your feet hip-width apart.
Keeping your knees softly bent, hinge at your hips, lowering the weight along your legs.
Maintain a straight, neutral spine as you lower until you feel a stretch in your hamstrings.
Contract your glutes and hamstrings to return to a standing position.
There are both psychological and physiological reasons why working out can feel more challenging in winter.
Reduced Motivation: Shorter days and less sunlight can disrupt your circadian rhythm and lower levels of serotonin, a neurotransmitter that affects mood. This can lead to decreased motivation and energy (3).
Comfort and Warmth: The simple appeal of staying warm and cozy indoors can be a powerful deterrent to getting out for a workout, particularly if it involves going out in the cold.
Physiological Response to Cold: When you first step into the cold, your blood vessels constrict to reduce heat loss from your skin’s surface. This can make your muscles feel stiff. Your body has to work harder to maintain its core temperature, which increases your overall energy expenditure (2).
Logistical Hurdles: Inclement weather, such as snow or ice, can make traveling to the gym or exercising outdoors unsafe or impossible.
Acknowledging these challenges is the first step. By creating a structured plan and understanding the “why” behind your winter workout, you can overcome these hurdles.
What Are Some Tips for Working Out in Winter?
To stay consistent and effective with your winter workout routine, consider these practical tips.
Prioritize Your Warm-Up: In the cold, your muscles and joints need more time to prepare for exercise (12). Extend your warm-up to 10-15 minutes, focusing on dynamic stretches such as leg swings, arm circles, and bodyweight squats to increase blood flow and muscle temperature.
Layer Your Clothing: If you exercise outdoors, dress in layers. A moisture-wicking base layer, an insulating middle layer, and a waterproof/windproof outer layer will keep you warm and dry. You can remove layers as you warm up (15).
Stay Hydrated: Cold, dry air increases water loss through respiration. Continue to drink water before, during, and after your workouts (16).
Focus on Nutrition: As the research on military personnel showed, energy demands can be higher in winter (7). Ensure you’re eating enough calories to support your training and muscle growth. A target protein intake of 1.6 to 2.2 grams per kilogram of body weight is a good benchmark for muscle building (17). Don’t forget to supplement with Vitamin D, as your natural production will be lower (6).
Set a Schedule: Treat your workouts like appointments. Having a set schedule reduces the likelihood of skipping a session due to low motivation.
Find a Training Partner: Accountability can be a powerful motivator. Training with a friend can help you both stay on track during the colder, darker months.
Have a Backup Plan: Have a winter workout at home plan ready for days when the weather prevents you from getting to the gym or exercising outside. This is a great time to explore different winter exercise ideas that don’t require a lot of space or equipment.
Frequently Asked Questions
Is it bad to work out in cold air?
No, it’s generally not bad to work out in cold air for healthy individuals. The body is effective at warming inhaled air before it reaches the lungs. However, for people with respiratory conditions, cold, dry air can be an irritant (15). It’s always best to listen to your body and consult a healthcare professional if you have any concerns.
Are muscles weaker in the cold?
Initially, yes. When muscles are cold, their ability to contract forcefully and quickly is reduced. This is due to slower nerve signaling and stiffer muscles (18). This is why a thorough warm-up is essential in winter – it increases muscle temperature and restores their normal function and strength capacity (12).
Which weather is best for the gym?
From a performance perspective, moderate temperatures are generally considered optimal. Extreme heat or cold places additional stress on the body to regulate its temperature, which can divert energy away from the muscles.
However, the best weather for the gym is any weather that doesn’t prevent you from getting there. Consistency trumps all other factors.
How cold is too cold to exercise?
There is no universal temperature that is “too cold”, as factors such as wind chill, humidity, and individual tolerance play a significant role. Most experts advise caution when the wind chill drops below -18°C (0°F). At these temperatures, the risk of frostbite and hypothermia increases significantly. It is crucial to wear appropriate layers and limit the duration of exposure (15).
The Bottom Line
Winter isn’t a season to put your fitness goals on hold. It’s a prime opportunity to focus on building strength and muscle. By understanding the unique physiological demands of the season and applying evidence-based training principles, you can create a highly effective winter workout plan.
Remember that consistency is the most important factor. Whether you train with heavy loads at the gym or lighter loads at home, a structured program paired with proper nutrition and recovery will lead to significant gains. Embrace the challenge of the season and emerge in the spring stronger and fitter than before.
