Minh benched a pretty hard 90kg x 3 at PTC last week. He said his best raw bench is 100kg. I have no reason to doubt him, everyone that watched his 90kg x 3 agreed. I wrote a newsletter about it.
November 2010 he made 162.5kg in a PA comp, then missed 167.5kg. So thats 62.5kg right there. He tells me he is now good for 175kg.
Seeing how his bench was 122.5kg at Nats in June, then 162.5kg in November, a mere 5 months later, I have no reason to doubt his 175kg claim.
His arch is insane. His Katana wont allow him to touch without his arch.
I have no doubt that my Raw bench would be up around 115-120 if I trained for it perhaps even more. When I was training for a Raw bench I could do 102.5 for 6 sets of 3
and probably 110 with a pause, maybe 107.5
that was when I hit the 122.5kg in a shirt with really no expertise.
After nationals I concentrated solely on equipped benching in a super katana -a shirt I had a year earlier said was impossible to use under IPF rules.
Things I needed to work on were:
Flexibility: in PA you have to have your feet flat on the ground when benching. this means one of two things. feet need to go forward or you have to have flexible hip flexors. I didn't like the first option so I stretched out my hip flexors 2 times a day for 3 months. Why the hip flexor and not the back? your back flexibility is restricted by how much you are willing to compress or extend your spine. Hip Flexibilty allows you to tilt your hips down towards the bench allowing more leg drive. Also the hip angle has to inversely correlate to the shoulder/trap angle in order to maintain tightness and not lose any energy stored on the eccentric phase (ie you want to use as much of the energy gained on the way down and channel it back up - efficient Stretch Shortening Cycle). It's all in the hips!
CNS: before any of this I never handled more than 122.5kg. So I had to prime my CNS to handle it. Reverse bands were good at the start, maxed out at 180 but I found they messed around with my line too much and as Jonnie pointed out before, the margin for error on a super K is 0.0000001%.
I ended up just doing partials with a perfect line and no boards, chains or bands.
Muscle recruitment: when I was training for the Raw bench it was all about speed from the stretch shortening cycle. Equipped is about control and maximum recruitment. With this I mean Lats, Tris, glutes, hammies, quads etc... of course this is important on a Raw bench too, but to a lesser extent and sequence of activation doesn't matter so much as your body will naturally activate the stronger ones.
SetUp: I work on this every day. I set my feet and hips first, sit upright straddling the bench, retract and depress my shoulder bladed then arch back while maintaining those mentioned positions. Grab the bar with a suppinated or underhand grip and dig my traps into the bench. Here I fine tune the angles of my traps to match my hips and my sure my feet a flat and flexing my calves as I dig into the ground and the bench.
LiftOut: With a shirt and arch its very hard to lift out without moving the shirt and/or your retracted and depress shoulders and also screws up the setup.
Pre Lift: Maintaining tightness, curl hamstrings, push knees out, shoulders beck and depressed, everything else tight
Pull down: Rows and chins with retracted scalps heavy weights 2-3 times a week. if you can't hold the retraction against the shirt you are going to tear your rotator cuff, a few times I got slack I would pull or strain my supra or infra or both.
Technique: i'll get back to this later because lunch time is over and sorry if I rambled on and all this doesn't make any sense
but this was just to point out that it is not easy to lift equipped, anyone that thinks they can get 75% just by chucking on a shirt
I will give them $100
