Two things stand out to me from this.
1. Chains off the ground for stablization work. I think that would really fry the core if you were walking the squats out as well.
2. They are hitting a opener 7weeks out with a reverse band. Not sure what strength band that would be, but 7 weeks is a long way out to me. I do something similar with a 3rd attempt, but about 3 weeks out.
