I'm doing a lot more running since the new year. When i was at the gym before lockdown the trainer did a test that measures body composition and my muscle mass had decreased from the previous time. She said it was because or the increase in running and that I needed to increase strength training and my protein intake. Looking at taking a protein powder but clueless about which one. I'm trying to lose weight so don't want one that will hinder that by being high in calories. Also, do I take it before or after my exercise?
Any advice much appreciated!
