Notes
Not swimming per se, but water running. This is my first time doing it, and it is very therapeutic since it allows for a decently hard workout without any pounding or pain. I definitely "felt the burn" since the water provides an extraordinary amount of resistance, even though your legs aren't (can't) moving as fast.
10 minutes easy.
10x 1 minute hard, 30 seconds easy.
5 minute cool down.
