Today's training tip comes from Charles Poliquin:
Leg Press vs. Squat
When comparing squats against leg press, squats are far more effective in increasing overall strength. However, there's some evidence to suggest that the leg press might result in more hypertrophy of the quadriceps.
One study showed that for the same number of reps, the leg press resulted in a higher amount of GH being produced than squats. As possible evidence, the leg press is the exercise of choice when it comes to speed skating, and I've personally worked with speed skaters whose legs made Tom Platz's look like Woody Allen's.
While I'm loathe to recommend leg presses instead of squats, I merely present it as an interesting discussion point.
