Any suggestions for a calf workout? The rest of my body is doing fine, but my calves are lagging. I usually do standing calf raises; 4 sets of 10-15 reps, and then seated calf raises in the same range. Sometimes I substitute the leg press machine to work my calves too. Any secret tips? I'd like my calves to match my upper body. Should I be running up hills like a mad man? Is the stair climber an option?
