I’m using an Adjustable Weight Bench for this exercise. Standing at one end of the bench with my toes and the balls of my feet on the bench’s framework. I’ve got my midsection firm and chest out. I’ve raised the back of the bench to full height so I can hold onto it.
I raise my heels as high as possible. Then lower them down again so they virtually touch the floor, so I can feel a stretch in my calves. I repeat this to complete my set.
