Why to you put your feet up on the bench? I always thought this was contraindicated.
If you've answered this before please refer me to the post.
This is more like a burn out set. The reason I put them on the bench it's because eliminates hip drive and forces me to regain balance which in turn it's an extra stimulus for triceps and core. Got this tip from a little, skinny guy who can out bench me at least for 50lbs. Scapulas aren't retracted through out the set so the ROM it's longer, still the I move the bar to my lower chest and finish up high as usual.
If you gonna try it be careful I almost felt off the bench the first couple of times, you will feel your abs/intercostal kicking in too.
