Fall Back into Fitness Day 3: Interval Cardio and Core


For the third day of the Fall Back into Fitness, we’re doing higher-intensity interval training and standing core work that targets the major muscles of the core, including the abdominals, lower back and glutes.

In the workout video, I’ll take you through a higher-intensity interval session that can be done in a small space using just a sturdy chair. I’ll show you how to adapt some of the tougher, traditional high-intensity, high-impact moves like mountain climbers, jacks, lunge jumps and more. We’ll be adding in some standing core work during our active recovery periods between intervals, too. Advanced exercisers, feel free to go all-out during these exercises.

Prefer to do your own thing? Awesome! Schedule 20–60 minutes of your favorite interval training workout, and include some targeted core exercises, if possible.
