Three laps of the track wrapped around 300 reps of posterior-chain grit.
3 rounds for time:
Run 800 m
50 Back extensions
50 Sit-ups
This is a long, steady grind that lives in your lower back, glutes, and lungs rather than your arms. Run at a controlled aerobic pace you can repeat three times, then break the back extensions and sit-ups into calm, unbroken-ish chunks so your midline never fully shuts down. The danger is redlining the first run and then crawling through the trunk work.
- · Back extensions performed on a GHD or hip-extension bench, full extension at the top
- · Sit-ups: shoulders to the ground, hips fully open at the top (AbMat standard)
- · Runs are 800 m each, completed before returning to the trunk work
- · Sub 400 m runs or a 1,000 m row if the 800 m is too much volume
- · Reduce to 35 back extensions and 35 sit-ups per round
- · Swap GHD back extensions for supermans or weighted hip extensions if the GHD is aggravating
- · Pick a run pace you'd be happy holding on round three and hold it on round one.
- · Break the trunk work before you have to: sets of 15–20 with short pauses beat grinding to failure.
- · Keep your feet moving into and out of the gym so the runs don't become rest.
