My N=1 . I ruptured a disk at L3 with bad form doing squats in 2010. Actually had muscle loss in my left leg. Did strictly machine lifts. More recently I actually got 1 on 1 coaching from Alan Thrall who you see in the video above. My thoughts;
- Keep the bar glued to your legs.
- Based on your video, I don’t see why you just don’t do deadlifts from the floor.
- Go slow and controlled as you return to the standing position, keeping the bar glued to your legs.
With proper form, I maxed out a 220 lbs for 5 reps with a standard deadlift at 155lb body weight at age 65 . Very slow and steady progress, you can get much stronger without injury.
(And they just closed the gyms in my state again )
