Okay so I've decided to start competing in powerlifting competitions to get ranked. First one will be USAPL this holloween or in decemember. I'm getting prepped for it now. I'm 5"10.5 168lbs - Going to be in the 165 weightclass I turn 17 in January I have a few questions on form. I've been going up almost everyday for the past 2-3 weeks in squats by either 10 or 20 pounds. I always do 5x5 rep-set. I now start at 325 and end at 405. My question is how far down is really the official form? I was always told parrell to floor is the right way, but I've seen some ppl go below and some go above. I can handle parrell at 325 but I need to work on my last sets getting and handling going lower. How low should I really need to go? I've been on a all powerclean routine, mainly because my coaches have never wanted us to do deadlifts. Right now I do 5x5 powerclean starting at 165 ending at 205. What would be a good start to practice deadlifts on, from that? I feel my back is pretty strong. I know my bench is horrible and I will handle that on my own. Lastly, if anyone could quickly explain ply shirts thatd be great. Thanks for the help.
