Well I found out I have mild scolosis a few years ago, around 22 degrees. After a year I came back to the doctor, and it not only wasn't worse, but even a few degrees less, although the doctor said it could have been an error as it's only a difference of a few degrees. Anyway, back has never bothered me normally or during sports or lifting. Also at the time though I hadn't even step foot in a gym and didn't even know what a deadlift even is so I have never asked him or just the normal doctor either.
1. Also I have never used a belt. I don't know if/when I need one, some people deadlift 225 or more with a belt, others don't use a belt at 405 so I don't know whether I need one or not? Actually speaking of belts, weighted dips and weighted pull ups are getting really akward to do with dumbbells...maybe I need a dip belt (like the belt with chains that you can put plates on)? If so not sure where to get it and also wondering how you carry it around because carrying chains and stuff all the time I would think would be inconvient?
2. Also today I just thought of the idea to film my squat and deadlift, and I think I see a big problem (aside from what you said about glutes being weak) in the squat, which I never noticed nor has anyone else, I have a butt wink which starts right as I go below parallel. What should I do? Coincidentally my friend has the exact same problem and it also happens right as he gets to parallel and goes below that.
Also deadlift seems like form is very good but there's two things I am not sure about:
3. Is it normal to feel your back after a set of deadlifts for like a minute or two (not pain but just feel it a lot)? It goes away before my next set but just wondering if it's normal or a sign that there's to much pressure put on the back, but if it is, I am not sure why because my form seems good. My back/lower back is never sore/hurts after a workout, pretty much the only muscle which ever gets sore is my hamstrings.
4. Also how do you avoid hitting the knees when lowering the bar down? The bar bangs into my knees sometimes and it's a bit annoying?
5.
a) Lastly there's something recently I noticed with barbell curls. I'm at 70lb right now, and after a few reps I start to feel a little pain in the pinky side of my wrist on my left hand. This never happened until recently, and actually when I warmed up with the bar (45lb) this doesn't happen, it also isn't like every time it's a bit inconsistent. Why is this happening and what should I do, I know of course you can use the Ez-bar or dumbbells but that's just a way to avoid the problem, how do you get your wrists to not bother you during barbell curls?
b) Also I've never payed much attention to this, but only after bicep curls, when I put the weight down right after I let go of the bar I feel a sharp pain for 2-3 seconds in the wrist and then it's gone. It never happens with any other exercise (even front squat which requires a lot more wrist flexibility), and it nevered happened during a set, just happens the moment I let go of the bar after a set?
Thanks for all the help!
