Your body builds muscle naturally in response to strenuous activity. But if you’re daily routine doesn''t involve challenging your muscles to grow
•Cardiovascular exercises that combine training with strength and flexibility. They are powerful and engage the entire body at once.
•High intensity interval training forms of cardio for a maximum of 20 minutes.
•In order for muscle repair itself after your weight-training sessions it needs a great quantity of protein. Some beginners don’t take enough protein and some more experienced guys take extreme amounts of protein powder or juice. Protein powder helps to increase your muscle. Eat those foods also increase your body weight.
