Matthews promises that these Apolo Ohno–style side lunges will get your heart rate up and work the entire lower body.

1. Stand with feet hip-width apart.
2. Leap out to the right with the right foot, crossing the left leg back behind the right, and touch the toes to the ground.
3. Repeat to the opposite side, leaping out with the left foot as you cross the right leg behind the left.
4. Alternate sides in a rhythmic swish that works the glutes, hamstrings, quads and calves (i.e., the areas that will inevitably be captured on film by someone trying to get a shot of their kids frolicking in the surf).
As a reminder, always consult your doctor for medical advice and treatment before starting any program.
