Workout Description

8 Rounds for Time (with a Partner) 4 Box Jumps (each) (34/28 in, switch every rep) 18 Deadlifts (245/170 lb) / Hang Hold* 7 Synchronized Bar Facing Burpees 36 Wall Ball Shots (20/14 lb, switch every 6 reps) * While one athlete performs the Deadlift, the other hangs from the Pull-Up Bar. Switch as necessary. Time Cap: 40 minutes

Why This Workout Is Hard

Eight rounds with a partner provides built-in rest during deadlifts/hang holds and wall balls, reducing individual volume. However, 245lb deadlifts (18 reps per round = 144 total), synchronized burpees, and 36 wall balls per round create significant cumulative fatigue across 40 minutes. The hang hold while your partner deadlifts taxes grip continuously. Partner format drops this from 'Very Hard' to 'Hard' for average athletes.

Training Focus

This workout develops the following fitness attributes:

  • Stamina (8/10): High cumulative volume — 32 box jumps, 144 deadlifts, 56 burpees, and 288 wall balls per team — demands significant muscular endurance across legs, posterior chain, and shoulders over the full duration.
  • Endurance (7/10): Eight rounds with a 40-minute cap and continuous partner work creates sustained cardiovascular demand. The hang hold and burpees keep heart rate elevated throughout, making aerobic capacity a primary limiter.
  • Strength (6/10): Deadlifts at 245/170 lb represent a moderately heavy load requiring real strength output, especially as fatigue accumulates across 8 rounds. The hang hold adds grip and lat strength demands simultaneously.
  • Power (5/10): Box jumps and bar-facing burpees demand explosive hip extension, while wall balls require a powerful squat-to-throw. However, the heavy deadlifts and volume shift the stimulus toward strength-endurance over pure power.
  • Speed (5/10): Partner synchronization on burpees and switching protocols add coordination pressure. Efficient transitions and rep cycling matter for time, but the 40-minute cap encourages steady pacing rather than all-out sprinting.
  • Flexibility (3/10): Basic hip hinge mechanics for deadlifts, hip flexion for box jumps, and overhead positioning for wall balls require moderate mobility but nothing extreme. Standard CrossFit range of motion applies throughout.

  • Wall Ball
  • Deadlift
  • Bar-Facing Burpee
  • Box Jump

Scaling Options

Deadlift weight: Scale to 185/135 lb (approximately 75% of Rx) for athletes who cannot perform 6+ unbroken reps with solid mechanics, or 155/105 lb for newer athletes. Box Jump height: Scale to 24/20 in, or substitute Box Step-Ups for athletes with knee concerns or limited jumping confidence. Hang Hold: Sub a Dead Hang from a lower bar or rings, or a Flexed-Arm Hang for stronger athletes wanting more challenge. If shoulder issues prevent hanging, substitute a Plank Hold for the resting athlete. Synchronized Burpees: Reduce to 5 reps per round or allow non-synchronized burpees to reduce coordination stress. Wall Ball weight: Scale to 14/10 lb or reduce to 30 reps (switch every 5) for athletes struggling with shoulder endurance. Volume: For newer athletes or those with limited partner experience, reduce to 6 rounds and cap at 35 minutes.

Scaling Explanation

Scale the deadlift if you cannot perform at least 5 reps unbroken with a neutral spine at the prescribed load — spinal flexion under fatigue across 8 rounds is a serious injury risk and must be avoided. Scale the box height if you are hesitant or inconsistent with your jump — hesitation costs more time than stepping up would. The hang hold is a grip and shoulder endurance challenge; if you have a shoulder injury or cannot hang for at least 20-30 seconds, substitute a plank immediately. Prioritize technique and consistent round splits over Rx weight — the intended stimulus is sustained aerobic output with heavy loading, not a max-effort strength test. Athletes should be working hard but never at the point where form collapses. A good target is completing all 8 rounds within the 40-minute cap with the last 2 rounds feeling genuinely difficult but manageable. If you finish under 30 minutes, consider adding load next time.

Intended Stimulus

This is a long, grinding partner workout designed to live in the 30-40 minute time domain. The stimulus is a sustained, hard aerobic effort with repeated bouts of heavy loading — think long steady engine meets strength endurance. The partner format creates built-in rest intervals, but the hang hold and synchronized burpees keep both athletes working simultaneously, preventing full recovery. The primary challenge is mental and metabolic: managing fatigue across 8 rounds while maintaining technique on heavy deadlifts and staying coordinated with your partner. Expect your grip, posterior chain, and lungs to be the limiting factors.

Coach Insight

Communication with your partner is the most underrated skill in this workout — establish clear signals before you start. On the Box Jumps, alternate every rep to keep a smooth rhythm; step down to protect your Achilles and save your legs for later rounds. For the Deadlifts, the hanging athlete sets the pace — the lifter should pull until their grip or form degrades, then switch. Aim for sets of 4-6 reps early and let the hang hold dictate natural break points. Do NOT ego-lift here; 18 reps of 245/170 lb across 8 rounds is significant volume. Synchronized Burpees are a great place to breathe — use a controlled, matching cadence rather than sprinting and waiting. On Wall Balls, switching every 6 reps keeps both athletes fresh; use the transition moment to shake out your arms. Common mistakes: going too fast in rounds 1-3 and dying in rounds 6-8, letting deadlift form break down late (rounded back under fatigue), and losing sync on burpees which wastes time. Target a consistent round split — if round 1 takes 4 minutes, aim to hold 4:30-5:00 per round through the end.

Benchmark Notes

Partner workout, eight rounds of 4 box jumps each at 34/28 in, 18 deadlifts at 245/170 lb while the partner hangs from the bar, 7 synchro bar-facing burpees and 36 wall balls (about 600 reps), with a 40-minute cap. An average team finishes in about 38 minutes, so finishing is L5; capped teams are graded by reps. An elite team (under 22:15) holds about 2:40 a round.

Modality Profile

4 movements: Box Jump (G), Deadlift (W), Bar-Facing Burpee (G), Wall Ball (W). 2 Gymnastics + 2 Weightlifting = 50/50 split.
