Inchworm to Beast

This drill strings a standing hip hinge to the beast position, giving you a hamstring stretch on the way down and a loaded core and shoulder hold at the bottom. Pulling into the knee hover instead of a flat plank keeps the quads and trunk fully engaged. It works beautifully as a movement-prep transition or a flowing conditioning exercise that links standing and ground positions.

How to do it

  1. 1

    Stand tall, then hinge forward and place your hands on the floor, bending the knees as needed.

  2. 2

    Walk the hands out step by step until you reach a strong plank position.

  3. 3

    Tuck the knees under and lift them an inch to settle into a braced beast hold.

  4. 4

    Pause in the hover, keeping the back flat and the hips level.

  5. 5

    Walk the hands back toward the feet and rise to standing.

  6. 6

    Repeat for the prescribed reps, moving with control at each stage.

Tips

  • Keep the core braced as you walk out so the low back does not sag into the plank.
  • Only lift the knees as high as you can hold without the hips shooting up.
  • Walk the hands, do not jump them, to keep the shoulders safe and the movement smooth.

Variations

Common mistakes

  • The knees lock out hard during the initial hinge, yanking the hamstrings instead of letting a soft bend share the load.
  • The hands stop a foot short of the feet on the way back up, so the back rounds to finish the stand instead of walking all the way in.
  • The feet stay glued together at push-up width through the walk-out instead of hip-width, which cramps the beast hold that follows.
  • Rising to standing by yanking the head and shoulders up first drags the low back into the finish instead of unrolling the spine last.
  • The wrists stay narrow and fingers closed during the walk, loading the joint unevenly instead of spreading the load across a wide hand.

Frequently asked

How many reps of the inchworm to beast should you do when you are new to the exercise?
Start with 2 sets of 5 to 6 full reps, treating the walk-out and walk-back as two deliberate halves rather than rushing between them. Add a two- to three-second hold in the beast hover before adding more reps.
How do I make the inchworm to beast easier or harder?
If the hamstrings are the limiter, bend the knees more during the hinge and walk-out so the stretch is gentler. To make it harder, add a short hold in a full plank before tucking into the beast, or slow the entire walk to a near-static pace.
What is the inchworm to beast good for and when is it a poor choice?
It links a standing hinge to a loaded core-and-shoulder hold, making it a solid movement-prep drill or a flowing conditioning piece that bridges standing and ground work. It is a poor choice for anyone with a wrist that cannot bear weight yet, or an acute hamstring strain that the deep hinge would aggravate.
