1. To know how muscles work, we should know how body works. Sleep is best medicine for obesity, but also best activity for muscle growth. That of course doesn't mean you can stop moving and your figure will shape just like that spontaneously during sweet rest in bed. It still applies that for muscle development you must exercise. But that is only beginning of whole process, because growth occurs only during deep sleep. Then they can finally relax, which allows better blood circulation. Moreover during sleep hormones are released that contribute to tissue renewal, which is key in formation of new muscle tissue.
2. And here is another proof that weight is like age – just a number. If someone is heavier, it doesn't mean they are less fit, it can be even completely opposite. Muscle mass affects how much you weigh. Muscles make up about 35 to 40 % of body weight. Reason is that muscle tissue is much heavier than fat tissue. So if you are just starting with fit lifestyle including not only new diet, but also regular exercise, you don't have to pull out your scale from dusty bottom of closet for a while yet.
3. Best fat burner is muscle tissue. If you want to get rid of excess kilos, and in your exercise plan were only cardio exercises until now, it is time to start with strength training. Body namely constantly processes energy for building and maintaining muscles, i.e. burns more calories.
4. Good news! Muscle growth is faster than loss of muscles. Although during longer break in exercise you can lose part of your muscle mass, in same time you can gain much larger. According to portal The Joint Chiropractic during one research after 2 months without training 23 % loss of strength occurred in participants, while in exercising group 47 % increase occurred in same time.
5. To muscle building path doesn't lead only through heavy weights. Small dumbbells allow you higher number of repetitions, you can perform movement in larger range, more precisely, so exercise with small weights is very effective. Muscles moreover develop when loaded in various ways, ideal is therefore to alternate training with low and high weight and bodyweight exercises.
