Is it better to train full body or split?

For most people, full-body training is better because it offers higher frequency per muscle group (usually 2-3 times per week), which is optimal for muscle growth ( 3 ). It’s also more time-efficient and flexible, as missing one session doesn’t mean neglecting an entire muscle group for a week. Split routines can be effective for advanced bodybuilders with very specific goals but are often less practical and forgiving for the general population ( 5 ).

Is it better to workout longer or harder?

It is typically better to work out harder (with higher intensity) for a shorter duration. Intensity, defined as the amount of weight lifted relative to your maximum capacity, is a primary driver of strength and muscle gain ( 25 ). However, if you are prone to injuries it is best to listen to your body and adjust your intensity as needed. Longer workouts often lead to accumulated fatigue, which degrades form and reduces the quality of your sets ( 9 ). A focused, intense 60-minute session will produce better results than a meandering, low-intensity two-hour session.

What exercises build muscle the fastest?

Compound exercises are the fastest way to build overall muscle mass. These are multi-joint movements that recruit large amounts of muscle tissue. The most effective muscle-building exercises include squats, deadlifts, bench presses, overhead presses, and rows. These lifts stimulate the greatest hormonal response and allow you to use the heaviest loads, providing a powerful stimulus for growth ( 10 , 16 ).

What to do in between full-body workouts?

The days between your full-body workouts are when the magic of adaptation happens. Focus on active recovery. This includes activities like walking, light jogging, stretching, or foam rolling. These activities increase blood flow, which can help reduce muscle soreness and speed up the delivery of nutrients to your muscles ( 26 ). Prioritizing sleep (7-9 hours per night) and maintaining a nutrient-dense diet are also critical for maximizing recovery and growth ( 27 , 28 ).
