I'm not juiced, I'm 41 years old and unless I do decided to take that option, the likelihood of my legs continuing to grow is pretty small. I like to squat, but I find one legged leg presses seem to be working well enough for me also, without worrying about knees, lower back or neck issues. I always thought squats were a great exercise, but fuck, if I can maintain what I have with some energy left over, by doing leg presses, why not?
