Holy triple-pronged cardio assault of Doom, Batman, that was humbling!
After heavy back skwatts we rounded off with a brisk metcon to get the heart working: 10 mins on the spin bike, standing, 10 mins running, 10 mins skipping (double unders optional).
Looked easy enough on the board. Wasn't. Its been ages since I did a spin session. My word did my calves feel it after a few minutes... which set me up nicely for the rest. Oof.
