"I can't even do a plank.. My stamina has really gone to waste."
Is it okay that my knees are hurting while I'm holding on...?
Planks are tough, but this is;; 💣
This has got to be the hardest for me as a beginner.
Try doing 3 sets of 50 seconds each on each side.
This is a really ridiculous exercise setting, Eva Eva.
Is plank funny??
