Beast to Crab
This is the signature animal-flow switch, and it teaches your body to move as one connected unit. Starting in a beast hover you unweight one arm and leg, rotate the hips open, and land in a crab facing the ceiling, then reverse it. The shoulders stabilize a shifting base while the obliques drive and control the rotation, building the kind of coordinated, full-body strength that carries into sport and daily movement.

How to do it
- 1
Begin in a beast hold with the knees hovering off the floor.
- 2
Shift your weight onto one hand and the opposite foot.
- 3
Rotate your hips open toward the ceiling as you lift the free hand and foot.
- 4
Pass through the turn and plant the free hand behind you to catch a crab position.
- 5
Set both feet flat and finish facing up in a low crab, hips near the floor.
- 6
Reverse the sequence to return to the beast, and alternate the direction you turn.
Tips
- Keep the traveling hand and foot light so the rotation stays smooth.
- Move through the transition slowly at first; speed comes once the path is grooved.
- Press hard through the grounded hand so the shoulder never collapses.
- Keep the hips low as you land the crab to protect the shoulders and stay controlled.
Variations
Common mistakes
- The catching hand lands too close to your seat, so the shoulder is crammed underneath you at the moment it takes your full weight; plant it about a forearm behind the hip.
- The travelling foot stays where it was and the turning body rolls over its own ankle; that foot has to swing through with the hips rather than wait for them.
- Both hands leave the floor at once in the middle of the turn, so the switch becomes a small jump; one hand should stay planted the whole way through.
- Socks or a slick floor let the planting hand skate out from under you at exactly the moment it takes your weight; bare feet and a grippy surface make this far less exciting.
- Once the turn starts, the knees drop to the floor and get picked up again on the other side, so the switch happens without the hover that made it worth doing.
Frequently asked
- How many beast to crab switches should you do when you are new to the exercise?
- Three rounds of six to eight switches, three or four in each direction, done slowly, or three rounds of 30 to 40 seconds if you prefer the clock. Rest a minute between rounds. Progress by pausing two seconds in each end position rather than by moving faster, and add rounds only once the path feels automatic in both directions.
- How do I make the beast to crab switch easier or harder?
- Easier: drop the knee to the floor during the turn and rebuild the hover on the other side, or split it in two by going beast, then a seated sit-through, then crab. A plain sit-through without the full crab is another step down. Harder: pause two seconds at each end, add a crab reach and a beast reach into the flow, or travel across the floor as you switch.
- Why train the beast to crab switch, and who should skip it?
- It teaches the body to rotate as one connected unit while the shoulders stabilise a base that keeps moving, which is why it is a staple of animal flow and a good low-impact conditioning finisher. Skip it until you can hold a beast and a crab comfortably on their own, and leave it out if the shoulders dislike bearing weight behind you. It builds coordination rather than strength or size.
