Also a fan of Core Advantage, although my physio just wants me doing squats, squats and squats, which Core Advantage isn’t too heavy on.
Am happy to combine the two, especially as (sorry, this is becoming my catchphrase) I’m trying to recover from lower back surgery as carefully as possible.
Currently doing sets of unweighted stuff (3×10) single leg squats, forward lunges, hamstring sliders and single leg bridges. I add in some resistance band monster walks because it always feels like it’s working the glutes!
Just started doing dynamic side planks (e.g. lifting hip from floor to plank position, then down) and also mountain climbers (sliding knee to chest from a push up plank position). That last one in particular rinsed me pretty fast!
Feeling so much better for all of these already. Hoping to build up to lower reps and higher weights in a month or so, just like to take it easy to begin with, I think twingy and spasmy backs are sometimes just a result of surprising your muscles with something new so they freak out a bit.
