At age 50 (last year) for the hell of it I did a "squat every day program". My max wasnt really any better or worse it just ended up being a lot of mediocre workouts. But I made it 64 days straight squatting every day..
I was just curious to see if I could do it and maybe make it 10-15 days before I fell apart. I surprised myself on what you can do if you just get after it..
