DOMS got me a little today, I did DE squats last night, so that could be the source also. My glutes and obliques are not happy. My quads are a little sore too, but nowhere near the others.
last nights DE squats (13" box):
lots of mobility work between the above sets, some glutial activation. Getting things warm loose and ready.
8x3@185: 60sec rest.
5x5 glute-hams w/10 kg bumper plate cradled to chest.
kept this one short and sweet.
