Introducing the Perfect Sit-Up, invented by the U.S. Navy SEAL who brought you the Perfect Push-Up.
The Perfect Sit-Up reinvents the sit-up by combining the upper ab crunch with the lower ab leg lift.
It's this one-two punch that gets you better, faster results.
Traditional sit-ups and crunches are hard to do and only effectively work at your abs, the upper abs.
But the Perfect Sit-Up targets and doubles the upper abs and the lower abs.
