Finish the program and your name gets carved too.

“Bybon, son of Phola, lifted me over his head with one hand.”

He didn’t wake up able to do that. Nobody does. You get there one rep, one session, one week at a time.

The plan

9 weeks. 3 blocks. 1 bell.

Five workouts a week, 30 to 40 minutes each, with a single kettlebell. Every block runs three weeks, and the rounds climb from 3 to 4 to 5. When a new block starts, you move up to a heavier bell.

Block 1

Weeks 1–3

Block 2

Weeks 4–6

Block 3

Weeks 7–9

The plan is a guide. Progress at the pace that’s right for you.
