Skinny To Fit: Possible Or Not?

While some people struggle with losing weight, others do their best to gain it by increasing muscle. So, is the transformation from skinny to fit possible? It is quite understandable, since keeping fit has a plethora of benefits.


Fitness can help you (8):

  • Prevent heart attacks and cardiovascular diseases.
  • Lower your blood cholesterol level.
  • Manage your blood pressure.
  • Recover easier and faster from hospitalization.
  • Prevent type 2 diabetes.
  • Lower the risk of having cancer.

However, this is not an easy task for the skinny of us to undertake. To this end, you will need a lot of time and perseverance. Everyone can build muscle mass if they follow a particular strategy and basic recommendations.

Compound Exercises > Isolation Exercises

First off, let’s look at the definitions of compound and isolation exercises.

Compound exercises are those that engage multiple muscles at the same time. These include squats (activate glutes, hamstrings, quads, calves, and abs), deadlifts (activate quads, hamstrings, glutes inner thighs, erectors, abs, obliques, and some other muscles), push-ups (activate chest, triceps, abs, and shoulders), and others (2).

Isolation exercises are those that engage only one particular muscle or muscle group. For instance, leg extension engages only quads, while standing barbell curls activate solely the biceps (1).

For those who want to go through the skinny to fit transformation fast, it is recommended to focus on compound exercises. These are fun to do and less time-consuming. Performing a squat, especially with weights, works on several groups of muscles at a time. Consequently, you will see the result sooner with compound exercises than with the isolation ones (1). However, that does not mean that you cannot spice up your workout with a few isolation exercises. What really matters here is to work your muscles to the fullest, leading to their fatigue. According to the American College of Sports Medicine (ACSM), three sets of 8-12 reps per exercise are sufficient to set your muscles on fire (3).

If You Have Persistence, Add Resistance

It is proved that resistance training has more of an impact than non-resistance training. The point of resistance training is to increase muscle against external resistance (5). The latter is usually indicated by the use of weights, but there are a number of other pieces of equipment as well, including resistance bands, benches, etc. Indeed, working out with equipment tends to exhaust your muscles much faster than without it.

Even those who have only recently embarked on their skinny to fit journey can apply resistance to their training. It is crucial, however, to regulate its intensity. There is a foolproof method to gauge the ideal resistance intensity for you. What you need is to calculate your one-repetition maximum (1RM), which is the maximum weight you can lift per one repetition. To do this, take the following incremental steps (7):

  1. Warm up.
  2. Do up to 10 reps of the chosen exercise with the weight that comprises 50% of your expected maximum.
  3. Rest for a couple minutes.
  4. Increase the weight to 80% of the expected maximum and do 3-4 reps.
  5. Rest for a couple minutes.
  6. Add another 10% and do a single rep. After a 2-minute rest, increase your weight by the last 10% and perform one rep. The weight you will manage to lift will be your 1RM.

It is important to perform such an intensity check once a week to keep track of your progress. In fact, the 1RM percentage of your resistance will decrease as you become stronger. As a result, you will have to increase your intensity regularly.

Engage Different Muscle Groups Every Time You Train

Since resistance training is very draining on your muscles, time for recovery is required. Weight lifting causes micro tears in your muscles, which need to heal up. If you continue training at the same pace, you will do more harm than good to your body. Ultimately, failing to let your muscles rebuild might lead to injuries that will prevent you from exercising for a long time (3).

The ACSM suggests a 3-day plan, during which you train the following muscles:

  • Day 1: shoulders, triceps, and hands
  • Day 2: glutes, hip abductors, quads, hamstrings, and calves
  • Day 3: biceps, abs, and back

In the beginning, you might need to take 1-2 days’ rest until the soreness in your muscles vanishes. As you advance in your skinny to fit goal, you will become able to work out without rest days. Nonetheless, it is recommended that you allocate time for rest, so that you do not get too tired.

Make Sure You Eat Enough Protein

The first and foremost function of protein is to build and repair muscles, making it a vital nutrient for those eager to change their shape from skinny to fit. Thus, eating enough protein will help your muscle tissues rebuild quicker, facilitating your muscle building prospects. Apart from repairing the tears in the muscles, protein generates energy for muscle contractions if in case fats and carbohydrates aren’t sufficient for this task (4).

Therefore, those who are willing to increase muscle should not forget to include protein foods to their diet. Such products include lean meat, fish, eggs, and dairy. Although there are numerous plant-based protein sources, only soy contains all the eight essential amino acids (4). Other plants with protein include lentils, seeds, nuts, spirulina, etc.

Despite playing an invaluable role in bulking up your muscles, protein can harm your body if over consumed. If protein constitutes more than 30% of your diet, your body will produce toxic ketones, overwhelming your kidneys. As a result of this, your body loses a great amount of water, leading to dehydration. Consequently, this is likely to decrease your muscle mass (10).

Ideally, the average grownup person should consume 0.80 g of protein per 1 kg of their body weight. However, if you do a lot of strength training, your protein intake should make up 1.4-1.7g per 1 kg of your body weight. Overall, your daily protein intake should be within the 15-30% boundaries (4).

Do Not Fast

Remember, your task here is not to lose weight, but to gain it safely through bodybuilding. Accordingly, it is not advisable for you to cut down on your meals. To grow your muscle properly, you need to have a nutritious diet, in which the amounts of carbs, fat, and protein are balanced. Similarly, you should not forget about vitamins and minerals, which will strengthen your body (3).

Balance is key to your diet, since overeating a particular nutrient can have a detrimental effect on your health. For instance, indulging in products rich in carbs can make your insulin level soar, thus weakening the growth hormones, responsible for muscle building. Likewise, you should make sure that your fat intake does not go beyond 30% (3). The same goes for protein.

Stay Hydrated

Water is vital for every human being, not only those who have commenced their skinny to fit transformation journey. To that end, it is suggested that one drinks about 10 glasses of water a day plus another 2 glasses before a workout. Then, one should have a glass of water every 15 minutes of intense training (3).

Love that the exercises are programmed…

Love that the exercises are programmed for age and ability. Quite honestly its great to have reminders to drink water, eat and weigh in etc.

An intelligent program

José S.
The exercises were intelligently planned to gradually check the limits of the practitioner. They make me sweat a lot and seem to be great to boost metabolism. I am surprised by their efficiency.

Great app

Being able to exercise in my own time and having a chance to see the results relatively quickly compared to once a week sessions at the gym gave me the drive to keep on following the routine. I love this app
