I’ve run Bridge, Strength I, II, PB I, II, Hypertrophy II for 2~3 years, while swimming 3 - 4 days a week( I don’t compete powerlifting)
I remember The Bridge felt really good my condition(mood) would sour most days. When lifting numbers wouldn’t go up, I had to change to 4 day templates from 3 day’s. It went ok made some progress but never felt great on my low back.
Provided I’ve already been running 4 days many times, would 3 day low fatigue still make progress? Or better off with 4 day low fatigue template?
Training time is not a concern for me. It would just be if 3 day lifting + 4 day swimming or 4 day lifting + 3 day swimming.
I would expect both templates to improve your strength and would pick the template that best suits your schedule. If you’re good with running 3 days per week, I’d start with that and graduate to the 4-day one afterwards pending results.
