Set up on the Hack machine by placing your feet close together low on the platform and your body (face-first) resting on the top rest pad. Get ready to release the safety hook mechanism to begin your initial raise. This is your starting position.
Release the safety and raise yourself up as high as you can using nothing but your toes. Keep your legs straight and as rigid as possible while doing this. Once at the top, lower back down to the starting position.
Finally, repeat the entire movement for the desired or prescribed number of repetitions.
Perform this exercise in a smooth and fluid motion
Keep your legs straight and rigid during the whole movement
Don't load the machine too heavy on your first set; always treat the first set as a warm-up set
SPECIAL NOTES & LEVEL of DIFFICULTY VARIATIONS
To increase the level of difficulty, slow down the movement or increase the weight.
This is a great exercise for the calves. It's comfortable to execute and hits your calves at a different angle compared to when you work them standing up completely vertical.
The hack machine is a great addition to any gym. However, these machines tend to be pricy so not every gym will have a hack machine. If your gym is one such gym then you will have no choice except to do a different exercise for your calves because it's next to impossible to improvise the angle of the hack machine in any other way on any other apparatus.
