Today I was at the gym and had switched up my routine so I can concentrate on legs more. I've been working out for about 4-5 months and have been skipping leg day almost every week because my routine was already 6 days on 1 day off. So I go into the gym today expecting my legs to be absolutely pitiful. I'm 18 and I'm 5'8'' 155lbs. So I start to squat and throw on 225 and do it 10 times easy. Throw on 275 and squat it 7 times. Wanted to go up more but this is the first time I've squatted heavy at all and the last time I squatted was probably 3 months ago. Then I get on leg press and do 540lbs 6 times. I was really pleased with the leg strength, but just based on my age, etc. Is this pretty good weight to be working with?
