Oh boy! This arms and glutes HIIT workout is a keeper. Using one pair of dumbbells I promise to toast your biceps and triceps, while we get your heart rate up with glute-specific cardio moves.

We start our workout with low impact moves and as we go I show you how you can spice it up if you want.

Day 4 of the 10 Day Legs & Booty Challenge.

Tools: moderate dumbbells, booty band (optional)
