Workout Description
5 Rounds for Time
5 Front Squats (255/155 lb)
15 Toes-to-Bars
25 Air Squats
50 Double-Unders
Why This Workout Is Very Hard
255/155lb front squats are near-maximal for average athletes, and 5 rounds compounds the challenge significantly. The leg-dominant structure is brutal: heavy front squats immediately followed by 25 air squats creates severe quad fatigue each round. Toes-to-bars demand grip and core under accumulated fatigue, while 50 double-unders require coordination when tired. Multiple limiting factors (strength, skill, endurance) hit simultaneously across 5 rounds with no recovery built in.

Training Focus
This workout develops the following fitness attributes:
- Stamina (8/10): High cumulative volume — 125 front squats total, 75 toes-to-bars, 125 air squats, and 250 double-unders — taxes muscular endurance across legs, core, and grip significantly across all rounds.
- Endurance (7/10): Five rounds of continuous movement including 50 double-unders and 25 air squats per round creates sustained cardiovascular demand. The for-time format pushes athletes to maintain aerobic output throughout.
- Strength (6/10): 255/155 lb front squats are heavy, demanding significant lower body strength. However, only 5 reps per round limits pure strength expression compared to heavier, lower-rep protocols.
- Flexibility (6/10): Front squats require thoracic extension and wrist/shoulder mobility. Toes-to-bars demand hamstring flexibility and hip flexor range. Combined, these movements impose moderate-to-high mobility requirements throughout.
- Speed (6/10): For-time format incentivizes fast transitions between movements. Double-under cycling speed and toes-to-bar rhythm are critical limiters, rewarding athletes who can move quickly under fatigue.
- Power (4/10): Double-unders require rhythmic wrist power and coordination. Front squats at this load demand some explosive drive, but the sustained rep scheme reduces peak power expression significantly.

Scaling Options
Weight: Scale front squats to 60-70% of Rx (155/95 lb) for athletes who cannot perform at least 3 unbroken reps at Rx weight with solid positioning. Sub goblet squats or a moderate barbell load if front rack mobility is an issue. Toes-to-Bars: Scale to knees-to-elbows, hanging knee raises, or V-ups to maintain midline demand. Reduce to 10 reps if grip or hip flexor fatigue will cause form breakdown. Double-Unders: Sub 100 single-unders or 35 attempts with practice double-unders mixed in. Volume: Reduce to 3-4 rounds for newer athletes or those with significant movement limitations. Rep scheme option: 5 Front Squats / 10 TTB / 20 Air Squats / 35 Double-Unders for a lighter stimulus.
Scaling Explanation
Scale the front squat weight if you cannot maintain an upright torso and full depth for at least 3 reps — a compromised front squat under fatigue is a back injury waiting to happen. Scale toes-to-bars if you cannot perform at least 5 in a row with control; kipping wildly and losing the bar wastes time and risks shoulder strain. The goal is to finish in 20-35 minutes — if your estimated time exceeds 40 minutes, reduce rounds or reps to preserve the intended stimulus of a hard sustained effort. Prioritize movement quality over Rx weight every time. Athletes newer to CrossFit or with limited gymnastics background should scale volume first, then load.
Intended Stimulus
This is a moderate-to-long time domain workout targeting 20-35 minutes of sustained effort. The combination of heavy front squats, gymnastics, bodyweight volume, and jump rope creates a hard sustained effort that taxes your legs, midline, and aerobic engine simultaneously. The primary challenge is managing leg fatigue across all five rounds — the heavy front squats will progressively compromise your air squats and double-unders, making this as much a mental grind as a physical one. Expect your lungs and quads to be screaming by round three.
Coach Insight
The front squat is the anchor of this workout — treat it with respect. At 255/155 lb, these should be heavy but manageable singles or small sets. Do NOT go unbroken on round one if that means grinding ugly reps; consider 3+2 or even singles from the start to protect your rack position and lower back. Toes-to-bars will degrade fast as your hip flexors fatigue — break these early into 8-7 or 5-5-5 rather than chasing unbroken sets and blowing up. Air squats are your active recovery; keep them smooth and rhythmic, don't rush. Double-unders are where time gets lost — stay relaxed in your shoulders, use a consistent cadence, and if you trip, reset immediately without frustration. The biggest mistake athletes make is going too hot on rounds 1-2 and dying on rounds 4-5. Aim for even splits. Transition quickly between movements — every second of standing around adds up over 5 rounds.
Benchmark Notes
Five rounds of 5 front squats at 255/155 lb, 15 toes-to-bars, 25 air squats and 50 double-unders. 255 lb is near an average athlete's front-squat max, so strength spreads the ladder wide. L5 (21:30-26:30) grinds the squats as singles. L10 (under 9:15) squats 255 at about 70% of max.
Modality Profile
4 movements total: Toes-to-Bar (G), Air Squat (G), Double-Under (G) = 3 Gymnastics; Front Squat (W) = 1 Weightlifting. 3/4 = 75% G, 1/4 = 25% W, 0% M.
