Shapeshifter is a workout that never stays in one form for long. Bear crawls flow into side plank holds, shoulder taps, slow climbers, a child's pose hold and an upward-facing stretch - nine stations that keep morphing your body from one shape to the next while your shoulders and core absorb the cost of every transformation.

The recurring bear crawl is the spine of the session, appearing three times to reset the pattern: hips high, knees hovering, moving on all fours - a position that demands coordination between opposite limbs while everything in between stays braced. After each crawl, the workout changes shape. First a side plank, loading one oblique chain at a time. Then a plank block of shoulder taps and slow climbers that strips away contact points and forces anti-rotation. Finally, the trick ending: the last two holds are a folded child's pose and an upward stretch - the workout shifts one more time, from work into recovery, lengthening everything it just spent three rounds contracting.

In the bear crawl, keep your knees an inch off the floor and your back flat enough to balance a cup on - small steps, no swaying. Stack your shoulders and hips in the side plank rather than letting your hips sag toward the floor. During the final two holds, breathe deliberately and sink into the stretch; recovery is a skill too.

Nine shapes per set. The form keeps changing. The effort never does.

Make it Harder: Double every 10-count to a 20-count.

Make it Easier: Perform the side plank from your knees and shorten the bear crawls.
