Hey Adam!
Your Squat form looks pretty decent my man. The only thing I can say with the squats are to keep your knees wide and outside your ankles on the way up and down (you were doing good at this - I'm just putting more emphasis on it).
Your Deadlift:
- You need to start with your butt a little higher (positioning your shoulder blades directly over the barbell; your shoulder blades are behind the barbell currently = no good). Next you need to try and "bend the bar" and point your elbows back (this will engage your lats and help keep the bar close to your body).
- On your way up, pressing through your heels, you want to push your hips forward and straighten your body by contracting your glutes (squeezing your cheeks). The glutes should be the main driver for a deadlift, not someone's lower back.
- At the top of the deadlift, you slightly arching your lower back. There's no need to do that.
Honestly you look like you're doing great!!! Just gotta clean up that deadlift form a little bit and you look golden!
