I usually put like a squat bar over my shoulders and do about 20 reps in 3 sets of toe touchies, i wouldnt use much weight about 10 on each side. or if you dont have a bar, just doing sets of toe toucies are still good, and even better if you put half your foot on a stair so you can di down further, but dont go on stairs with a weighted bar, you could easily fall backwards... i did this and in about two weeks my calfs mustve gained about 2 more inches around them, but i stopped, or i at least dont do them as much because i dont see what large calfs' purpose are.
