There’s a routine some people swear by. It’s one of those where you feel the burn. Introducing: Greg Plitt’s MFT28 – Abdominal Assault.

It has 8 exercises:

  1. 3/4 sit ups
  2. Side twists (aka russian twist)
  3. Ankle biters (aka alternate heel touchers)
  4. Rocky sit ups (aka air bike)
  5. Cocoons
  6. Side planks
  7. Bottoms up
  8. Elbow to knee

Doing 3 rounds of these (each of ~10-15 repetitions) should have you feeling the progress immediately afterwards. Let us know how you like it in the comments!
