Chris Hinshaw of CrossFit Aerobic Capacity takes athletes through a fun, competitive warm-up ahead of a running workout.
The warm-up consists of 6 rounds of single-unders with a heavy Zeus rope, 30 seconds on, 30 seconds off.
The challenge: Find your number on the first set and match it in each subsequent round—without looking at a clock.
“What I love about this is that it truly is something that anybody can do,” Hinshaw says.
