just from the dips, i can see that you're rolling your shoulders forward, which means lack of mobility and also you're elbows aren't pointed directly behind you or pointing to the ceiling when at the bottom of your Dip, which isn't so low. that's a good place to start from and also the FG pullups seems like you're elbows/forearms/wrists aren't mobile enough or strong enough to start from a dead hang.
just some refinement to minimize injury, improve form to maximize the effort invested ![]()
