I'm looking forward to the military bench comp as well. I've never done that style of bench before. Does it reduce your bench a lot not being able to arch?
I suspect this will vary a lot from bencher to bencher. If you are weak off the chest or feeling very unstable, this lift will probably kill you. For those who use an extreme arch, this lift may well at least double the range of motion. as well. On the other hand, some people will probably find the difference to be marginal. Once the results are in, we will see whether there is a lot of discrepancy from lifter to lifter or whether the cut is fairly uniform.
The Military bench is all about minimizing the impact of technique to test RAW full range of motion strength (this will impress all the regular folks in the gym who do not understand the essence of powerlifting). I see a lot of potential in having Military bench meets from time to time; if you really start working on the lift I suspect it will boost strength off the chest in the regular bench.
I'm obviously no expert, but I would be hitting the dumbells and cambered bar hard for this meet in addition to the obvious military bench sets. I'll make sure to get into one of the meets next year since I can't make this one.
Yes, not arching does affect your strength unless you're like me and benching with a minimal arch anyway.
Indeed, it is even possible that you will bench MORE in the Military bench as that is closer to your regular style.
Inversely, I always wonder what poundage increases you would get were you to actually use your legs to push into the ground.
If you check out
Måns benching, you will find that he only touches the ground with the tip of his feet to meet the requirements of the rules. Måns is more of a powerbuilder/bodybuilder so this is very understandable, getting into a powerlifting bench will probably feel as alien to him as the Military bench will for many a powerlifter...
