I live in India and have joined 4-5 gyms in last 4-5 years in different cities. Every time people do and also suggest me to do exercise that target only one muscle per day. e.g. on Monday only biceps ...
Since muscles grow when they are resting, has anyone got any tips, supplements or anything at all that will help my muscles grow more effectively during resting period?
What are the benefits of taking shorter rest times in between sets? If I am capable of doing an extra rep or two if I rest for 1 minutes instead of resting for 30 seconds, which is more beneficial?
