AMRAP 4 mins (extendable): 15 Thrusters (100/65 lb), 15 Chest-to-Bar Pull-Ups. Complete 90 reps (3 rounds) within the window to earn 4 more minutes, repeating indefinitely.
Primary movement: Thrusters/C2B
Open 13.5 closed 2013 with the Open's cruelest invention: a 4-minute Fran-paced sprint where finishing 3 rounds buys you 4 more minutes, forever. For most athletes it's the most intense 4 minutes of the year - a genuine sprint with a hard stop. For the elite, it became an infinite ladder: Games athletes famously extended through 16, 20, even 24 minutes of continuous thrusters and chest-to-bars. Your score is total reps whenever the music stops.
| Level (Reps) | Men | Women |
|---|---|---|
| beginner | 45 | 40 |
| intermediate | 65 | 58 |
| advanced | 90 (extension!) | 80 |
| elite | 150+ | 130+ |
Total reps; 90 within 4:00 earns the first extension.
Where does your Open 13.5 Rx land?
Log it once and the app places you on this table automatically, then tracks the trend.
Decide your identity before 3-2-1: sprinters (no realistic extension) go near-unbroken from second one and empty everything by 4:00. Bubble athletes pace the first 2 rounds deliberately - 8-7 thrusters, 8-7 C2B - to arrive at round 3 with 75 seconds, because making the extension with nothing left just delays the ending. Transitions of 2 seconds; in a 4-minute window, rest is measured in reps lost.
Scaled: 65/45 lb thrusters and chin-over-bar pull-ups, same extension rules.
