My session today consisted of:
4x3 Quad Squat
4x3 Trinity Squat
3x3 Spinal Rock (sit up version)
Eccentric / Isometric contrast:
4x3 1L SLDL
3x3 Spinal Rock (Pike version)
I added one set per exercise for the four main exercises. Funnily enough this didn't seem to make the session much more taxing. I definitely feel ready to explore some other challenges, which will happen with the start of my next cycle next week Friday.
