Workout Description

Why This Workout Is Medium

Three 3-minute AMRAPs on a calorie machine is moderate volume with built-in recovery. The 3-minute work intervals are short enough that most athletes can sustain high intensity, and the 3-minute rest periods provide meaningful recovery between rounds. The limiting factor is cardiovascular capacity and leg power, not skill or complex movement patterns. Average CrossFitters can complete this as prescribed without significant scaling, though fatigue will accumulate across the three rounds.

Training Focus

This workout develops the following fitness attributes:

• Endurance (9/10): Three 3-minute AMRAPs on a calorie machine demand sustained cardiovascular output. The repeated efforts with brief recovery test aerobic capacity and the ability to maintain high heart rate across multiple rounds.
• Speed (9/10): Sprint cycling or rowing speed is the primary performance metric. Quick, explosive leg turnover and rapid movement cadence are essential to accumulate maximum calories in three minutes.
• Stamina (8/10): Continuous machine work for three 3-minute blocks requires significant muscular endurance. Legs and core fatigue accumulates across rounds, demanding sustained power output despite mounting fatigue.
• Power (8/10): Maximizing calories demands explosive leg drive and rapid pedaling or rowing cadence. Power output directly correlates with calorie accumulation, making explosiveness critical for performance.
• Strength (1/10): Calorie machines require minimal absolute strength. Movement is primarily about generating power and speed rather than moving heavy external loads or resisting maximal forces.

Scaling Options

This workout is inherently scalable — the machine does the adjusting. Any athlete at any level can perform max-effort calories on a machine. However, modify the structure if needed: reduce to 2 rounds instead of 3 for beginners or those with cardiovascular limitations. Reduce the AMRAP window to 2 minutes with 2 minutes rest for newer athletes still building aerobic capacity. Switch machines based on injury or availability — rower is low-impact and great for most, bike is easiest on the joints, ski erg challenges the upper body. Athletes with lower body injuries should choose the ski erg or rowing with light leg drive. Upper body injuries may prefer the bike.

Scaling Explanation

Scale the round count or duration if you cannot sustain meaningful output through all three rounds — if your round 3 calories drop more than 20-25% compared to round 1, the volume is likely too high. Prioritize intensity over duration: it is far better to do 2 truly hard rounds than 3 mediocre ones. The goal is to feel genuinely challenged by the end of each window. If you finish a round and feel like you could have pushed harder, you likely paced too conservatively. Athletes recovering from illness, injury, or those newer to high-intensity conditioning should reduce to 2 rounds and focus on learning their pacing limits before increasing volume.

Intended Stimulus

This is a short-burst, high-output sprint workout repeated three times with full recovery between efforts. Each 3-minute window should feel like an all-out effort — think 90-95% intensity with lungs burning and legs screaming by the final 30 seconds. The rest-to-work ratio is 1:1, meaning you should arrive at each new AMRAP feeling recovered enough to match or beat your previous round. The primary challenge is conditioning and mental toughness — pushing hard when your body wants to quit, and then doing it again twice more.

Coach Insight

The key is consistency across all three rounds — aim to match your calorie output in round 1, 2, and 3 rather than blowing out round 1 and dying in round 3. Start at about 85% effort for the first 30 seconds to build into your pace, then commit fully from the 30-second mark onward. On the rower, drive hard through the legs and keep your stroke rate between 26-30 SPM — more power per stroke beats a frantic spin. On the bike or ski erg, find a damper setting that suits your output and stay seated to conserve energy. On an assault or echo bike, resist the urge to sprint the first 20 seconds — it will cost you. In the final 30-45 seconds of each round, give everything you have. Track your calorie count each round and use it as a benchmark to compete against yourself.

Benchmark Notes

Total calories across all 3 rounds is the score; the 3-min rest allows solid recovery so each interval should be near-max. L5 (~35 cal/round × 3) reflects a solid intermediate athlete pushing hard on a bike, rower, or ski erg without pacing to preserve output.

Modality Profile

Calorie Bike is a monostructural cardio movement. It is a cyclical, continuous effort on a stationary bike measured in calories burned, making it 100% Monostructural (M).
