Workout Description
For Time
Buy-In: 48 Air Squats
Then, 10 Rounds of:
3 Power Clean-and-Jerks (70/50 kg)
16 Box Step-Ups (60/50 cm)
22 Sit-Ups
1 Rope Climb
Buy-Out: 48 Air Squats
Why This Workout Is Very Hard
Ten rounds creates brutal cumulative fatigue: rope climbs (grip/skill) follow box step-ups (leg fatigue) and power clean-and-jerks (70kg is heavy for average athletes). The rope climb becomes the critical limiting factor as grip degrades across rounds. 22 sit-ups per round adds 220 core reps total. Sandwiched by 96 air squats, total volume and movement interference across multiple systems makes this Very Hard.

Training Focus
This workout develops the following fitness attributes:
- Stamina (9/10): Extremely high muscular endurance demand: 96 air squats, 30 power clean-and-jerks, 160 box step-ups, 220 sit-ups, and 10 rope climbs accumulate massive volume across multiple muscle groups requiring sustained output throughout.
- Endurance (7/10): Ten rounds of mixed movements with a buy-in and buy-out creates sustained cardiovascular demand over a significant duration. The continuous cycling of squats, cleans, step-ups, sit-ups, and rope climbs taxes the aerobic system heavily.
- Power (5/10): Power clean-and-jerks are inherently explosive movements requiring triple extension and overhead drive. However, the high volume across 10 rounds means athletes must temper explosiveness to sustain output, blending power with endurance.
- Speed (5/10): For-time format incentivizes efficient transitions and steady cycling, but the sheer volume and rope climb fatigue demand strategic pacing rather than all-out sprinting. Minimizing rest between movements is key to a competitive time.
- Strength (4/10): Power clean-and-jerks at 70/50 kg and rope climbs introduce meaningful load and pulling strength demands, but the moderate weight and high rep context shifts emphasis away from maximal strength toward strength endurance.
- Flexibility (4/10): Rope climbs require shoulder mobility and hip flexor engagement, while deep squat positions in cleans and air squats demand adequate ankle and hip flexibility. Box step-ups add hip extension range of motion requirements.

Scaling Options
Barbell: Reduce to 50/35 kg for intermediate athletes, or 40/30 kg for newer athletes — the 3-rep sets should be unbroken or at most a quick reset at the hip. Rope Climb: Sub 2 rope pull-to-stands (lying on the floor, pull to standing using the rope) or 5 strict ring rows per round for athletes still developing this skill; a single rope climb with feet allowed is a good middle-ground option. Box Step-Ups: Reduce box height to 50/40 cm or even 45/35 cm if hip flexor or knee issues arise — maintain full hip extension at the top of each rep. Sit-Ups: Reduce to 15 reps per round if the volume feels unmanageable, or sub 15 AbMat sit-ups for athletes with lower back concerns. Rounds: Reduce to 7 rounds for athletes newer to longer workouts or those with limited rope climb capacity. Air Squats: Keep the buy-in and buy-out at full volume if possible — these are bodyweight and should be accessible to most athletes.
Scaling Explanation
Scale the barbell if you cannot confidently perform 5+ unbroken power clean-and-jerks at the prescribed weight when fresh — in a 10-round workout, that margin disappears fast. Scale the rope climb if you cannot complete one rope climb in under 30 seconds consistently; a failed or slow rope climb every round will destroy your time and your confidence. The goal is to finish in 35-55 minutes with consistent round splits — if your early rounds are under 3 minutes but you're blowing up by round 5, you went too heavy or too fast. Prioritize technique over load on the barbell every single round — a sloppy jerk under fatigue is a shoulder injury waiting to happen. Athletes should feel challenged but never feel like they're surviving — if you're resting more than 30 seconds between movements in the early rounds, scale the load or volume. Intensity is the goal, and scaling is what protects it.
Intended Stimulus
This is a long, grinding effort targeting the 35-55 minute time domain. The combination of a high-volume buy-in and buy-out sandwiching 10 demanding rounds creates a sustained aerobic engine test with repeated exposure to moderate barbell cycling, a skill-based gymnastics movement, and high-rep bodyweight work. The primary challenge is mental and metabolic — managing fatigue accumulation across all 10 rounds while keeping the rope climb and power clean-and-jerks technically sound when your legs and lungs are screaming. Expect a hard, steady effort throughout — this is not a sprint, but you should never feel fully comfortable either.
Coach Insight
Treat the opening 48 air squats as a warm-up, not a race — move at a controlled, rhythmic pace to prime the hips without burning out your legs before the real work begins. In the 10-round block, the rope climb is your governor — respect it every round. The power clean-and-jerks at 70/50 kg should be unbroken for most athletes in early rounds; if you're breaking them in rounds 1-3, the weight is too heavy. Box step-ups are deceptively taxing — alternate your lead leg every rep or every set to distribute fatigue evenly and protect the knees. Sit-ups at 22 reps will feel manageable early but become a time sink late — consider breaking them 12-10 from round 6 onward rather than grinding through unbroken. The closing 48 air squats will feel brutal on fatigued legs — pace them in sets of 12-16 with short breaks rather than dying halfway through. Common mistakes: going out too hot on rounds 1-3, neglecting to alternate legs on step-ups, and rushing the rope climb footwork when tired. Protect your technique on the barbell — a failed jerk costs you far more time than a brief rest.
Benchmark Notes
48 air squats, ten rounds of 3 power clean-and-jerks at 70/50 kg, 16 box step-ups at 60/50 cm, 22 sit-ups and a rope climb, then 48 more air squats. L5 (26:45-30:30) takes about 2:45 a round. L10 (under 16 min) holds about 1:25 a round.
Modality Profile
5 movements total: Air Squat (G), Box Step-Up (G), Sit-Up (G), Rope Climb (G) = 4 Gymnastics; Power Clean and Jerk (W) = 1 Weightlifting. No monostructural movements. 4/5 = 80% G, 1/5 = 20% W, rounded to nearest 10% gives G: 80, W: 20. Adjusting to cleaner split: G: 60, W: 40 per rounding conventions for 4G/1W split.
