This is prob a beginner Q but i dont the answer, due to some injuries im starting cross-over into powerlifting.
Say your bench & DL are good but your squat is lacking, when youre told to do a specific exercise to “bring it up” does it replace your squat for a designated period of time, say 4 weeks, and then you go back to your squat after that month & re-test your PR?
Example: Im having trouble getting out the hole & was advised to do 3-5 sets of 3 box jumps, pregressively getting higher - would they be accessory work to my squat or replace it for a month?[/quote]
Accesory work for your squat.
Think about the implications of using them as a substitute for squats. Why would you abandon the movement you are trying to improve?
Most people have trouble getting out of the hole. That’s why you see people in gyms quarter squatting. Could mean a couple things in your case, but I suspect you just need to tighten up, buckle down and put in the time in the gym.
In a year’s time, if you are squatting more but still feel slow coming out of the hole, are you really going to be that bothered by it? Assuming your technique is solid we coach lifters all the time to turn that part of their brain off that is feeding back how “quick” the weight is moving. Just stay tight and get it done.
We had a stiff leg DL contest a couple weeks back (just being idiots) and I did a single with the weight that was on the bar. The two guys before me missed the weight. I went to do a double to rub it in and basically got crushed. When I stood up they told me they couldn’t believe I tried another rep after how slow I ground the first one. Truth is, all I knew is the weight went up and I wanted to put an exclamation point on it. I had no concept of how slow the rep moved.
Bottom line, put together a solid plan, run it for 6-8 weeks, evaluate your progress and do it again.
