Dude I can do 3 or 4 plates for 20 reps. In fact I can do more, calf raises are easy even a newbie should be getting into heavy weights pretty fast. On a standing calf raise I do 6 plates for reps.
Don't listen you'll find out 10 years down the road when your knees and shoulders are shot.
I disagree.
Am I reading this right; you say 6 plates on STANDING calf raises isn t putting stress on the knees?
