The core seems to be a tough spot to whittle down. Whether you are carrying a spare tire or you just don't have that hourglass figure you envisioned, we have the moves to tone you up! A good core includes a strong back, so we picked moves that work both the front and the backside of the abdominal wall. Now, we do use a variety of equipment for these moves, but it's well worth it. You can also sub out medicine balls with weights as you see fit! Do each of the seven moves for one minute each, rest for a minute, then repeat!

What you need:

  • stability ball
  • medicine ball
  • sliding disks

Fish Crunches: When doing this move, it's important to make sure you're lifting yourself using your core and not your arm that's resting on the ground. For full instructions, click here.
