My husband stepped up my workout game with Power Block Dumbbells. Each block is adjustable by 3 pounds up to 24 per hand. Lock in the weight you need and leave the rest behind; This one block saves the space of 8 separate weights! I'm ready to start round 2 of the #FBBooty workout and these PowerBlocks will power through the Fitness Blender sets. I will see massive results in my ass by Closer To The Sun 4. Suns out, buns out, till the fun runs out.
