Calf expert - the only feature that I can compare to any pro.
Seated (4-6 sets)- take a lightly wide position, go deep into the movement and always slow. Use a weight you can get 8-10 easily but 15-18 makes it hurt like hell.
Standing(machine)(4-6 sets) - this is the key for overall development, not size. Use a weight you can get at least 18 with, but it burns. Take a normal shoulder width stance but place your feet so they point out, almost like 45 degree angles. Do 10-15 slow and deep. Without hesitation or rest, move them to the exact opposite, 45 degree angles in. Repeat. Then again, without rest, place them straight and close. Repeat.
Leg Press Machine(3 sets) - go fairly heavy, use a full range of motion, one leg at a time. Never drop below 10 reps because if you do then the weight is too heavy and your control will hurt your progress.
Standing(dumbbells)(3 sets) - this is for burn outs only. You can't get a strong foothold and usually have too much focus on control and the weight in your hands to give it a necessary push. Use a high rep range to pump them out before calling it quits...like 18-30.
Train calves heavy on leg days and light 3 days later with arms, abs, or shoulders. Give it 6 weeks without any delays - take before and after photos to gauge your progress.
Good luck!
