Using one dumbbell, you will get your heart rate up and hit all the muscles in the body (especially the core). This is super easy to follow, and modifications are shown on our modified screen on the right of your screen.

This is also Day 2 of the 25 in 25 Challenge too! YAY!

And if you're sore from yesterday's strength-based workout, this cardio-based workout will help get the blood flowing and the muscles feeling better.

Trainer's promise.
