Hey everyone! I tried to search for a answer to this but couldn't really find a specific answer. So I hope this hasn't been asked a 100 times.
When I train, only some muscle groups get sore and others don't. Like yesterday was leg day, and I did my normal routine. 3 sets of squats 3 sets of seated leg press, and 3 sets each of leg extensions, leg curls and calf raises. But today only my calves are sore? My hamstrings and quads are fine. And it happens on upper body too. My chest,back and biceps always get sore but my triceps and shoulders never do.
So is this normal? or the muscles that don't get sore, am I not stressing them enough? I always use a heavy enough weight to keep my reps in the 10-12 range. Anyway does anyone have some advice or anything? Thanks in advance everyone!!
