Thanks for pointing that out Coach! I can actually do it the way you described it, but I injured or strained my biceps tendon about two months ago by being stupid by doing planche push-ups cold without warming up in the long term and there is still some pain to this day if I do planche holds or lock out. So I'm doing planche push-ups this way so I don't aggravate my tendons until they fully recover. They're close to fully healed I think.
I still have to say though that I highly doubt being able to full planche push-ups the correct way would bring me close to 2xBW bench press. Even Gregor said it wasn't anywhere close for him. Was the full planche push-up = 2xBW bench press based on your personal experience or from speculation?
@Tavis G: You might be right. Did you personally feel it a lot in your chests when you do PL or PLPU? Please do tell us how much you can bench when you achieve straddle or full planche push-up.
@Hari_Seldon: Thanks for telling me the correct technique! When I was doing them I was retracted, but my lower back was flat or had a normal lumbar curve on the bench. Do I have to maximally arch my back and wouldn't that sort of be cheating by reducing the ROM or does that activate the right muscles? Should we protract the scapulae during the concentric or should they be fully retracted for the whole ROM? Thanks!
For the PLPU, I know what you mean when you say legs rising before chests. I am always conscious about that and try to minimize it. Honestly though, my legs didn't rise that much and that fast to give much momentum for the push on most of the ones in my video. They also don't shorten the lever length, but instead lengthen it when you are piked unless you start arching and that's when they shorten it. It's also partly because I knew I was a bit piked at the bottom and I tried to straighten it out by lifting my legs which ends up with higher hips. I say my biggest flaw is the piking with hips higher than shoulders and I need to learn to unpike the torso rather than lift the legs to straighten out with leveled hips.
Also, what are your thoughts on carryover from full planche push-up to 2xBW bench press? What was your experience with PL and PLPU to bench press strength?
@alex87: Thanks for the tips! Is it the best to bench that way or is it just to get more numbers on the bar in powerlifting? Did you have a background and lot of experience with bench press before achieving straddle planche push-up?
