I just do pause box squats right now. I spent a number of months doing DE squat work and using accommodating resistance but neither really had much effect so I dropped them and only use it as a change up now. The band work actually seem to cause more issues than provide benefits. I use a shoulder width, high bar placement.
I love doing chins and dips in the same workout. How many reps do you get before you have to rest? I am up to 10 on chins and 20 or so on dips.
That's interesting. Box squats didn't help my training whatsoever. The 2 biggest things that helped my squat was pause squats (3 seconds in the hole) and reverse band squats. Reverse band squats did several things at once... CNS overload, speed work, and also a confidence builder. It allows you to lift more than you may try if you're lifting by yourself b/c as ROM increases weights decrease and vice versa.
Have you ever tried squatting with a wider stance and a lower bar placement?
