This exercise lasts for 60 seconds, but replaces 1.000 sit-ups!
Would you like somebody to give you a power to slow down the time so you can make 1.000 sit-ups in only 1 minute?
Thanks to this video you can learn how to make an exercise in only 60 seconds that replaces 1.000 sit-ups.
Take the same position as in the video, but make sure your body is straight and your upper arms are under an angle of 90⁰.
Tighten all the torso muscles and breathe normally. Start with 15 seconds a day, then pass on 30, so at the end you reach at 60 seconds.
The most advanced and most persistent trainees could extend the time in 90 seconds, but the recreationists shouldn’t pass over 60 seconds.
