Workout Description
5 Rounds for Time:
10 Kettlebell Swings (70/55 lb)
29 Burpees Over the Kettlebell
Wear a Weight Vest (20/14 lb) throughout
Why This Workout Is Very Hard
The weight vest transforms an already demanding workout into a serious challenge. Five rounds of 29 burpees (145 total) is brutal volume on its own, and the vest adds constant load throughout every rep. The KB swings at 70/55 lb with a vest compound grip and posterior chain fatigue. Estimated 30-45+ minutes for average athletes, with the vest preventing any true recovery between rounds.

Training Focus
This workout develops the following fitness attributes:
- Stamina (9/10): 145 burpees and 50 kettlebell swings across 5 rounds demands exceptional muscular endurance. The weight vest amplifies fatigue in the shoulders, hips, and legs, making sustained output extremely challenging.
- Endurance (8/10): Five rounds of high-rep burpees combined with kettlebell swings and a weight vest creates sustained cardiovascular demand. The volume and added load elevate heart rate significantly throughout the workout.
- Speed (6/10): For-time format incentivizes fast transitions and efficient cycling of burpees. Managing pace across 145 burpees while wearing a vest requires strategic speed to avoid early burnout.
- Power (5/10): Kettlebell swings are inherently explosive hip-hinge movements requiring hip power. However, the high volume of burpees dilutes the power stimulus, creating a mix of explosive and sustained output demands.
- Strength (3/10): The 70/55 lb kettlebell provides moderate loading for swings, but the primary demand is endurance-based. The weight vest adds constant resistance but does not constitute maximal strength effort.
- Flexibility (3/10): Kettlebell swings require hip hinge mobility and thoracic extension. Burpees demand basic shoulder and hip flexibility. Neither movement pushes extreme range of motion requirements.

Scaling Options
Weight vest: reduce to 10 lb for both genders or remove entirely for newer athletes or those with shoulder/back limitations. KB swings: drop to 53/35 lb if form breaks down, or substitute Russian swings (eye level) instead of American swings. Burpees: reduce to 20 burpees over the KB per round to keep total volume manageable, or substitute regular burpees (no lateral jump) if coordination over the bell becomes a safety issue. Volume: reduce to 3-4 rounds if the athlete is newer or the time cap would be exceeded significantly. Rep scheme alternative: 10 KB swings / 15 burpees over KB for 5 rounds for athletes still building aerobic base.
Scaling Explanation
Scale the vest if an athlete cannot maintain a consistent burpee pace due to shoulder fatigue or breathing restriction — the vest should add challenge, not cause movement breakdown. Scale KB weight if the athlete cannot complete 10 swings with a neutral spine and strong hip drive. Scale burpee volume if the athlete's projected finish time exceeds 45 minutes — the stimulus is sustained hard effort, not survival. Prioritize movement quality on swings above all else, as fatigued KB swings with a loaded vest are a recipe for lower back strain. The goal is to keep athletes moving continuously with short, planned breaks rather than long unplanned stops. If an athlete is stopping for more than 15-20 seconds at a time by round 2, they need to scale load or volume.
Intended Stimulus
This is a long, grinding chipper-style workout designed to test your mental toughness and aerobic engine under load. Expect a 25-45 minute effort that lives in that uncomfortable middle zone — not a sprint, not a slow grind, but a sustained hard effort that demands you stay composed when your lungs and legs are screaming. The weight vest adds constant systemic stress, making every movement harder and every breath more labored. The primary challenge here is mental: 145 total burpees over a kettlebell while wearing a vest will break athletes who don't have a plan. The KB swings serve as a brief but demanding power reset between massive burpee sets. Adaptation targets include aerobic capacity, muscular endurance, and mental resilience under fatigue.
Coach Insight
The burpees are the workout — treat the KB swings as active recovery and move through them efficiently but not recklessly. For the swings, hinge hard, drive with the hips, and keep your core braced tight against the vest. Don't rush the swings and blow up your lower back before 29 burpees. For burpees over the KB, find a sustainable rhythm immediately — a choppy, inconsistent pace will cost you more than a steady, boring one. Aim for a consistent step-out burpee if needed rather than a fast-and-crash jump approach. Land softly, step or jump laterally over the bell, and keep moving. The vest will make the jump portion of burpees significantly harder on your shoulders and chest — expect the push-up phase to slow down in rounds 3-5. Pacing strategy: treat round 1 like round 3. If you're flying in round 1, you're going too fast. Break burpees into mental chunks — sets of 10, 10, 9 — and never fully stop. Common mistakes: going unbroken on burpees in round 1 and dying in round 3, losing hip hinge mechanics on swings when fatigued, and not accounting for how much the vest slows transitions and breathing.
Benchmark Notes
In a 20/14 lb vest, five rounds of 10 kettlebell swings at 70/55 lb and 29 burpees over the kettlebell. The burpees are 80% of the time. L5 (14:15-16:30) holds about 12 vested burpees a minute. L10 (under 7:50) holds about 25.
Modality Profile
Two movements: Burpee Over Object is Gymnastics (bodyweight movement), Kettlebell Swing is Weightlifting (external load). 1 G + 1 W = 50/50 split.
