For now, his solution is having a protein shake after playing sports or swimming. On the metro ride home after a game in mid-April, he says, “My cardiovascular health is up to the mark. I need to do something about my muscle mass, but I really don’t like the gym and weights. Can you show me some body-weight exercises that can help me build muscle?” I showed him push-ups, burpees, squats, lunges and some pull-up variations, and told him he needed to perform a combination of any three, with at least one lower-body exercise, at least thrice a week. He made a mental note, but I doubt he has managed even a single session yet.
