Sig Klein's Dumbbell Challenge
Sig Klein liked to call the two-dumbbell clean and press "THE ONE BEST EXERCISE" because it was so simple but also incredibly effective for
building upper-body strength and power. Klein suggested to begin this exercise with 20 pounds less than your two-arm press and build from there.
Back in the 40's, he questioned whether there were a dozen athletes in the country who could do 10 clean and presses with a pair of 75 pound dumbbells. That was body weight for Sig. This was a worthy challenge back then and still is today.
