Sorry if you feel that I come off as cocky, I’m just amazed at some of the statements in this thread.
The people here saying that it isn’t physically possible for him to get up with the dumbells after those sets are exactly the ones that need some education in physics.
In short, he’s mastered a technique to let the momentum of the dumbells help him get up. If you can’t see that from watching the videos then you don’t understand, nor can envision, the physics involved.
I bet you are probably not using the same technique as him in returning the weights because of one or more of these reasons:
you’ve never had to because the dumbells you use are not that heawy compared to your bodyweight
you go to failure and are not able to get the dumbbells into a position so that you can use their momentum to get up
you simply decide to drop the dumbells on the floor
LOL. Putting them on your knees from the laying position is allowing momentum to help you up by allowing you to put force forward (towards your knees). Putting them on your chest is not. That is WHY most of us put them on our knees to both kick them into position and to let them down assuming failure has been reached.[/quote]
The technique he used with the lighter 100lbs weights in the first video wasn’t as efficient as the one he used in the latter video with the 110’s which is probably the reason he got a little help from his friend. Notice the way how he puts the weights on his chest (the weights are straight up) and the way he lifts his legs and lets the weight fall forward helping him get up.
With the right timing this provides enough momentum for him to get up with those heawy weights (at least with a little help from his friend). Think about the way the db’s turn 180° from the time they are on his chest to the time he has got up. The first 90° of that rotation is when they are falling which provides momentum for the sit up.
On the other hand if he would have put the weights flat on his chest like is much more common and then tried to do a sit up he would not have gotten up without a lot of help from his friend because he would not have that momentum.
