Alright, so I've started working with what some call "the power crew" at my gym. It's comprised of two older ex power lifters and a guy a bit older than me whose started working out with them. Since then I've been trying to get my bench up with them and one of the older guys mentioned to me that I need to work on my lats more (which I've been trying to do, but I always have issues with back exercises and don't feel sore). Anyways, I can pick up a ton of weight, but when it's sitting on my chest I struggle getting it off, so my weak point is at the bottom of my press, so looking for tips on strengthening that area of my press and maybe ideas on why I'm not feeling any muscular soreness or help with it in general.
Edit: Also would like to note, since working out with them my right side (and I'm right handed actually) has been falling, first time this has happened, but also first time I've had partners so I'm able to overload beyond max to get my body used to the weight.
