Box Pace-Modulation Square Runs
Set up a large square using 4 cones or footballs. Run at 65% pace along the first two sides, explode into a 100% maximum sprint along the third side, and recover with a slow jog/walk along the final side to complete one circuit; perform 4 laps per set.
Key points
- Pace yourself at a steady 65% aerobic tempo across the first two sides of the grid
- Accelerate violently into a full 100% sprint along the designated third straightaway
- Use the fourth side for active walking/jogging recovery to lower heart rate before the next lap
- Complete 4 continuous laps per set, resting 1-2 minutes between sets for 3-4 total sets
Common mistakes
Sprinting too early during the 65% aerobic phase or jogging the sprint straightaway.
