Three couplets · two rounds · twelve minutes · feet that carry you
Bag on the knees; keep raising for the full minute without stopping — count clean reps.
Easier no weight · Harder heavier
One second up, one second down, all the way through — stop at the last clean rep.
Easier hold a support · Harder one leg

Easier less tension · Harder more tension
Five with the toes turned in, five straight, five turned out; full range each.

Easier forward · Harder slower and higher
Two bags, up on the toes; walk tall and stay high the whole hold.
Easier bodyweight · Harder heavier
Each couplet: 60 s scored → the loading set → 10 s to move on. Done at 12:00.
