Do not train calves as an afterthought. Treat calves like they are bi's, tri's or chest. In other words train them consistently and intensely. Speaking of intensity, workout two is quick and painful. It consists of two giant supersets.
Most gyms have their calf equipment situated next to one another.
You will need to occupy three different pieces of equipment for this routine. You can use the donkey calf machine, seated calf machine, standing calf raise machine, leg press calf raises or angled calf raise machine. This workout consists of doing the first exercise, then jumping on the next piece of equipment, then jumping on a final piece of equipment. Each set will be with a weight that you can handle for at least 10 reps, but always go until failure. As soon as you are finished your first set immediately jump on the next two machines and do the same thing.
