The pushup may at first appear outmoded by other, more complex fitness regimes. However, Alden Mills, a seven year veteran of the U.S. Navy Seals and a former platoon commander, discovered that focusing on functional exercise could decrease the number of injuries his Seals incurred while on the job.

He revamped the Seals’ elite training methods and developed a tool that helped them do bedrock exercises more correctly and effectively.

The Perfect Pushup allows arms to rotate naturally while doing pushups, garnering deeper muscle contraction that increases an athlete’s overall performance while protecting the shoulders and arms from injury. The Perfect Pushup’s newest model (V2) features an ergonomic grip, a rubber, anti-slip bottom and better all-round construction; Mills’ company, Perfect Fitness, was recently named #1 Consumer & Product company by Inc Magazine. $40.
