If you’ve been living under a rock, interval training is pretty popular (HIIT classes are everywhere!). I’m all for short, intense cardio bursts that spike my heart rate, but speed intervals on a cardio machine…FOR THE LOVE OF PIZZA PLEASE DON’T MAKE ME.
When I am able to trick myself into doing high intensity cardio, there’s one token workout I turn to: Speed 10. Why? It’s over in less than 30 minutes.
