15-15-15 workout
45 minutes of cardio split evenly across a spin bike, an elliptical and a treadmill
A simple gym cardio session: 15 minutes on a stationary bike, 15 on an elliptical or cross trainer, then 15 running or walking on a treadmill. Changing machines every quarter hour keeps the session from dragging and shifts the load across different joints and muscle groups, with the first 30 minutes low impact. There is nothing special about the exact machines or timings; the appeal is that it needs no plan, works at any pace, and gets a full 45 minutes of steady cardio done. It builds endurance rather than muscle, so people usually pair it with strength work.

Actor · Friends and The Morning Show
The cardio session she described to InStyle: a 15-minute spin, 15 on the elliptical, 15 running, a name she coined herself and called old school, a way to chase herself around a gym. She has since moved to lower-impact training (see her Pvolve entry), so treat this as an earlier chapter.
