So I finally upgraded from my inzer blast and went to a single-ply Rage-X. All I can say is wow. However, although my numbers were high (My raw two board record is about 330 and with the shirt today hit 385 and a miss with 405) I still have many questions because I do not lift with anyone who knows much about shirts.
To start off I'll just state what I believe of bench shirts in terms of fitting and technique. To put my bench shirt on, I have somebody pull the shoulder back on to my arm as far as possible and have someone pull down on front (however the front never seems to stay down once I lay down, even with locking my belt). I also make sure when I'm putting it on that the arm seam aligns with my elbow, then to build a bit more tension I rotate the sleaves away from my chest. I'm not really sure how to make it fit under the armpit perfect so I am basically asking for someone to comment on how the armpit should fit as well as what to do about how it fits across the collar (over the chest) and if what I stated above is correct.
Now for my technique I try to get up on my traps (I'm a big archer) and get my legs out wide for a good drive while still being able to keep my ass down for the most part. However, with the shirt pulling my shoulders forward, I fell its hard to tighten my upper back and squeeze my upper back like I can on a raw bench. To start after my lift off I begin by pulling my elbows straight back to build tension across the chest, then when I'm down to about the height of a 4 or 5 board I begin tucking my elbows, tucking them harder and closer to my body as I come down farther trying to maintain maximum pressure in the chest and armpit/ trap area. Once I touch the board, I press straight up with my triceps, and once the weight starts moving I bring the bar back over my face a bit and flare my elbows at the top. Is this correct? Although I felt it was a strong lift today, I feel I could be a bit more explosive out of the bottom. As a rather skinny person (5'10" and 175 pounds) my triceps and lats are much stronger than my shoulders, and I had some slight shoulder pain after. It wasn't an unhealthy feeling, but it was sore in my rotator area so I'm wondering if my technique was incorrect somewhere, or if its just my body getting used to the new weight.
Any input would be helpful and appreciated. Thanks for the help ahead of time! Lift Strong!
