I've suggested this before, and I have to urge you readers out there to try this challenge and see how much it kicks your ass!! My first trial last week I managed 386 full squats, using only my body weight. Today I focused hard and crushed my previous mark with 505 squats!!! Man, my knees are wobbly and my legs are just shakin', but I'm lovin' how pumped my legs, and hips are. It even works the back and abs. Total beast of a workout in only 20 minutes. This will definitely be a mainstay in my workout routine. Adam, better get to those squats and bump up that 592 you posted at the end of January. I'm coming for ya!! Muwahaha!!!
