Nah it’s a new fad of a massive circuit of training. Run, cycle , rows, lunges , box jumps, burpees , it’s like a Sparta race format but all around that type of training.
Yeah actually fasted for 24 hours . 12 hours before the cardio and another 12 hours after.
Don’t do this all the time , but health benefits and tightening up a bit. Lost 1.5kg over 24 hours. Put most of it back on in the following 12 hours
