The combination of the two can achieve the effect of muscle building and shaping. But in the process, we need to pay attention to the reasonable arrangement of exercise amount and time. The subject's height and weight are moderate and light, and the muscle-building exercise should be moderate intensity, and the strength exercise should be done 3-5 times a week (once every other day), each time 1 hour. It should be emphasized that the muscles in the exercise area are more sour and hotter when the weight is small for many times and the interval between each group is 1-2 minutes, which shows that it is effective. Let everyone know that the most important thing to gain muscle is diet. Muscle fullness requires protein's reasonable intake and adequate sleep, so that the body will improve well in a year or so. Yoga can actually practice muscles, and many advanced poses can't be completed without a certain amount of strength. But the main function of yoga is plasticity. Doing yoga for about half an hour after each strength exercise helps to make muscles form more perfect lines instead of stiff blocks. Congested muscles, when pulled, will change their internal tissues. Doing more muscle-building exercises will make the muscles of the whole body tighter, and many of them will be limited when doing yoga, so we should explore the balance between the two. Everything should not be too difficult.
