I'm in my early 30s and just started lifting again after about 5 years of not doing it. I used to be able to bench 220 for reps and squat about the same. Not alot in other words. One reason I wanted to do this again is I realized there was a direct correlation between my tone and my grip strength. My buddy who lifts and does construction has serious grip strength, and has that loud chiming SRV type tone when he plays. Now that I started again, I did 20 bicep curls with 30 pounds and man am I feeling it the next day. Any of you guys notice this?
