Key Takeaways
Often, individuals find themselves wondering how to bring their bodies into perfect shape, without losing their hard-earned muscles. It's not an easy task, but it's doable. Yes, often during the sculpting process, we simply lose weight instead of shedding fat and exposing the muscles, which, of course, is not the desired outcome. To counteract this, one should take into account several tips.
Meal Plan

Our smart diet generator creates a tailored meal plan in 3 minutes based on the recommendations in this article.
Speed does not yield advantages
It is never recommended to drastically decrease caloric intake at the beginning of the sculpting period. If someone does this, fat tissue will undoubtedly be burned, but muscles will also be burned. To gradually decrease subcutaneous fat tissue, it is necessary to gradually decrease caloric intake. In the first week of the sculpting period, it is sufficient to lower the intake by 100-200 kcal. The loss of fat tissue in a very short time does not lead to a more attractive figure with highlighted muscles. Set realistic goals and achieve them slowly and systematically. The expected result is a weight loss of 0.5-0.8 kg per week. During the sculpting, patience and caution are most important.
Moderate level of cardio training
Cardio training is undoubtedly an excellent method to increase daily energy expenditure and consequently reduce excess fat, but prolonged and excessive aerobic exercise prevents proper body rejuvenation. Prevention of muscle mass loss is possible by ensuring adequate rest. If without regular aerobic exercise there is no decrease in subcutaneous fat content, this may be due to irregularities in a diet that is poorly balanced or low in calories.
Choose intervals
Interval training is the ideal solution when it comes to burning fat and building muscle. Regularly performing interval training sessions throughout the week will ensure maximum fat burnout and stimulate natural processes of lipid metabolism. However, it is important to remember that interval training is a much more challenging method and requires some level of experience and knowledge about the body. While doing interval training, we should always exercise caution. If we decide to incorporate it into our weekly training program, we must give up some aerobic training sessions. It is not advisable to perform three aerobic and three interval-based training sessions in a week, as this can lead to disruptions in the regeneration processes and loss of muscle mass. Simply alternating cardio training with intervals and vice versa will suffice. This will be an additional incentive for the body to burn fat and reveal muscle structure.
Keep in Mind Adequate Nourishment
During the sculpting phase, some athletes consume less than 1800 kilocalories a day, and sometimes even less. This is an inappropriate approach. A sudden reduction in calorie intake leads to a rapid loss of muscle mass and slows down the process of fat catabolism. The body starts to defend itself against hunger and tries to store everything in the form of fat tissue, which is not the goal of those who engage in sports. Of course, everyone is different, and what helps one person may not be a good option for another. Nevertheless, it is most important to remember that a negative caloric balance should never be equated with a fast.
Do not abandon your usual strength training
Sculpting a figure also encompasses a properly constructed diet that takes into account a calorie deficit and a combination of strength and endurance exercises (cardio/interval). What does strength training look like when it comes to building muscle mass? It likely involves average or low repetitions and weights within the 70-90% CM range. These are the stimuli that cause muscles to grow. If someone does not perform these exercises, they deprive the body of the main stimulus for development. How can the body maintain a high level of muscle tissue if there is no longer high weight? It begins to regard muscles as unnecessary, as something that consumes excessive amounts of energy, and since that is the case, it should be eliminated. Do not give up on training loads. In one session, it is best to perform mainly exercises with high loads and additional exercises with higher repetition counts. The muscle tissue will be appropriately stimulated, and the body will not begin to break it down because it will consider it necessary.
