For abs core…and much more
RKC/captain morgan Plank circuit
Start in a side plank and do rkc captains Morgan planks for 10 seconds each leg(so do both legs, that’s 20 seconds), then transition to a rkc single leg/arm front plank (thats two more transitions, up to 40 seconds), then transition to the other side for rkc captain Morgan side planks (two more transitions, up to 60 seconds) then finish with a 10 seconds standard rkc plank.
I start my workout with a series and it makes my hips feel so damn good. Then I finish my workout with another series.
Great preventative maintenance strength builder for adductors, abductors, hips, shoulders, core/abs.
If the description is confusing I’ll try to get a video for you next time I train.
