Jog: 3 minutes
Butt kickers: 1 minute
Rev up your run and kick your heels up towards your glutes, pumping your arms back and forth as quickly as you can for 60 seconds [as shown].
Single-leg squats: 1 minute
This sculpting move helps develop balance while toning your legs (and is better than using a leg press machine). Stand on your right leg, left foot flexed and lifted a few inches off the floor, hands behind your head. Push your hips back and bend your right knee to lower into squat [as shown]. Extend your right leg to return to standing, keeping left foot lifted the entire time. Repeat as many times as you can for 30 seconds, then switch legs.
Repeat the full set one more time (2x total).
