Ever notice how sore your feet get while doing calf raises? That’s because your foot muscles and tendons work hard just to keep you balanced on your toes. Calf Buster reduces that work, transferring it to your calves, giving them more focused and powerful muscle contractions.

35° ankle torque

With Calf Buster, you’ll get the same range of motion as doing a regular calf raise without having to bend your foot. With 35 degrees of tensioned ankle rotation, you’ll experience deep muscle burn over the full range of your calf contractions.

Add Extra Support

Maximize the effectiveness of your workout by attaching the waist strap to your Calf Buster for added support during high-intensity reps. Attach the waist strap to your Calf Buster for added support during higher weight tension reps. *Waist support strap included with every purchase.
