The Calf Curve

True, calf raise platforms aren't complicated... DIYing takes a few bucks and about an hour (if that). That said, the design matters. Some can increase calf activation and offer a much better lifting experience than others. After trying 2x4s, 45 lb plates, square-style blocks, wedges & ramps, they all had issues; mostly limited range of motion and foot slippage during the stretch. We decided to DIY our own block using 2 pieces of wood, a 4" PVC pipe, and grip tape. The round design felt a lot better... until the PVC cracked during a heavy set. So we drew up what is now our Calf Curve®, tested and refined the prototype, drove Mike's GMC truck over it a few times to confirm it wouldn't fail, filed the patent, and are now proud to release it!
