Add some isometric holds to your strength training to build lean muscle while burning calories. This at-home workout, lead by Autumn Calabrese, requires a medium set of dumbbells. It's only 20 minutes, but trust us — you will feel worked.
This is one of my favorite workouts so far!
I love the stretching at the beginning and how focused and effective the workout is until the end.
Just building my resistance to ace it every time!
Thanks so much!
