AEROBIC POWER [LACTATE THRESHOLD]
STIMULUS
- Overview: This classic conditioning triplet blends movements with an explosive hip drive with aerobic power. The kettlebell swings and box jumps will load the hips and calves, while the run tests your aerobic efficiency pace under accumulating leg fatigue.
- Each round should take 3:00-4:00.
- Kettlebell Swings: Start with the kettlebell between your legs. Using your hips as the power source, swing the kettlebell overhead until it is directly over your ears, shoulders, hips, and ankles. Your arms should be straight and extended at the top of your rep. These should be able to be completed unbroken in the first round, then strategically broken if desired. If you need to break more than once, the weight is too heavy.
- Box Jumps: Must reach full lockout/extension of the hips & knees at the top of the box. Step down off the top of the box - no rebounding.
- Intended Intensity: RPE 7-8
- Target Loading: Moderate
- Fitness Attribute Improved: Aerobic Power [Lactate Threshold]
- Target Score: 12-15 Minutes
* If time-capped, add 1s to your score for every incomplete rep. (200m = 1 rep)
STRATEGY
- Quickly settle into your overall pace. This isn't a workout where you want to come out hot. Your first and last rounds may be slightly faster than the second and third, but not by too much (10-15 second variance). Your overall time will benefit from consistency across all four rounds with a final surge at the very end.
- Kettlebell Swings: Aim to go unbroken each round. Snap your hips hard and keep your arms relaxed.
- Run at a sustainable pace, but don't use it as recovery. Push the final 400 meters.
