Hey Dean,
Unconventional, though interesting start! A few things first - I've never used the app but it seems to put out good direction that obviously translates to the user. Nice work on the self-cueing, it sounds like you've got right ideas. And secondly, I dig the vlog format and am looking forward to watching the videos develop. Very entertaining!
However, there really is a
lot of great and thorough content in the book that has either been overlooked, or has yet to be read. For example, the book describes the exact steps to your first workout. Now I'm not saying that every single word in the book is gospel, but the misunderstanding of how the first workout is
supposed to go has allowed you to be a little too ambitious with weight selection, and a little too shy with volume. The procedure is to add weight to the bar until the bar speed slows, then you continue to do two more sets of 5 at that weight. No big deal, you're definitely off on the right foot.
Really nailing form is tough the first time around, especially without the instant feedback of an in-person coach. It's takes time, but is far from impossible. You aren't doing the viewer too many favors with your camera angles, though. Read through the stickies on the technique forum, as well as the Coaches Q&A, for lots of good info on things like how to best video your workout, tips/tricks for linear progression, and more.
I will give you some insight on my perspective of your lifts;
Squat: You need to sit back more, bend over more. It also looks like you could benefit from a good dose of
thoracic extension. However, it's hard to tell too much from behind this wall of plates. A rear 45° oblique not only gets the plates in storage out of our way, but allows us viewers to identify any knee/back/everything issues.
Press: Nice start on the press 2.0. Don't initiate the hip movement by pulling them back, but rather a sharp
extension of the hips (hips forward). The return-to-normal movement from the hips forward position provides the initial oomph to the lift.
Bench: Narrow your grip and inch or two. Tuck the elbows more. This movement is traditionally the most practiced, and also has the least margin for error. Either way, looks pretty good!
Deadlift: The bar is too far in front of mid-foot. An inch or two when you're standing up right, as opposed to already grabbing the bar. I think I heard you cue yourself to sit or lean back for this lift. Leaning back drops the hips, which in turn degrades pulling mechanics. It reduces leverages, as well as pushes the shins forward to only reinforce the bar-forward-of-mid-foot issue. When viewed directly from the side, the bar should be
behind your shoulder.
Overall, nice work on your first session. Keep it up.
