This 30 minute total body workout with Keri requires dumbbells and a medball. If you do not have access to a medball, you can use one dumbbell for all the exercises, except the medball slams. Mimic the slamming action of this and you will still get a cardio burst.
You'll need a set of dumbbells and a kettlebell. If you do not have access to a kettlebell, you can use one dumbbell, just make sure you have a good hold on for the kettlebell moves, but it will work the same!
