Workout Description

Why This Workout Is Easy

This workout uses low-intensity, low-skill cardio (ski erg) at 60-70% effort with generous rest built in. The 6x:45 block has a 1:1 work-to-rest ratio, followed by a 3-minute recovery. The second block uses 1:1 work-to-rest with progressive effort but remains submaximal. Total volume is modest (~9 minutes work), no strength demands, and ample recovery prevents fatigue accumulation. Average athletes complete this comfortably as prescribed.

Training Focus

This workout develops the following fitness attributes:

• Stamina (8/10): Repeated ski erg intervals with minimal rest between rounds challenge muscular endurance of legs, core, and pulling muscles. Sustained output across 10 intervals builds significant work capacity.
• Endurance (7/10): Extended ski erg work at 60-70% effort for 10 total intervals tests aerobic capacity and cardiovascular sustainability. The moderate intensity and cumulative duration demand solid aerobic base.
• Speed (5/10): Moderate pacing with structured rest intervals. Building effort in second block requires pace management, but not sprint-level cycling or rapid transitions.
• Flexibility (2/10): Ski erg requires basic hip and shoulder mobility in a seated position. Minimal range of motion demands compared to compound movements.
• Power (2/10): While ski erg involves some explosive leg drive, the 60-70% effort level and focus on consistency prioritizes steady output over explosive power development.
• Strength (1/10): Ski erg is a low-resistance, high-repetition movement requiring minimal force production. No maximal strength demands present in this workout.

Scaling Options

This workout is largely self-regulating due to its effort-based nature, but here are adjustments for different ability levels. Newer athletes or those with limited ski erg experience: reduce the first block to 4 rounds instead of 6, and keep the second block at 3 rounds instead of 4 to manage total volume. Athletes with lower aerobic base: extend the rest in block one to :30 instead of :15, and match rest to work in block two (1:00 on / 1:00 off stays appropriate). If a ski erg is unavailable, substitute a rowing ergometer, BikeErg, or echo bike using the same time intervals and effort targets — note that calorie outputs will differ across machines so track meters on rower or RPM feel on the bike. Athletes recovering from shoulder or low back issues should substitute the BikeErg or air bike to eliminate the spinal loading pattern of the ski erg. No load adjustments needed as this is purely machine-based output.

Scaling Explanation

Scale if you find your output dropping more than 10-15% between your first and last interval in either block — that is a sign the rest-to-work ratio is too aggressive for your current fitness level. Athletes should prioritize mechanical consistency over hitting big numbers: a smooth, repeatable stroke at moderate effort is far more valuable than a high-output round 1 followed by degraded form and declining splits. The goal is to finish block two feeling like you left one round in the tank — not completely spent. If you are new to the ski erg, the learning curve on technique is real, so scale volume and focus the first few sessions on body mechanics rather than output numbers. Anyone experiencing sharp low back discomfort during the hip hinge should stop and sub to another machine immediately.

Intended Stimulus

This is an aerobic capacity and pacing discipline workout sitting in the moderate time domain — roughly 15-20 minutes of total work spread across two distinct blocks. The first block (6x:45/:15) trains your ability to hold a controlled, repeatable output with minimal rest, building aerobic base and metabolic consistency. The second block (4x1:00/1:00) shifts toward a progressive effort ladder, asking your aerobic and aerobic-threshold systems to work harder with each round. The primary challenge here is mental and mechanical — resisting the urge to spike early, staying honest with your pacing, and executing clean, efficient movement when fatigue accumulates. Think of it as a steady engine session with a controlled burn at the end.

Coach Insight

Treat the first block (6 rounds) like a metronome — pick a calorie or meter target in round 1 and defend it every single round. At :45 on and :15 off, there is almost no recovery, so going out hot will cost you by round 3 or 4. Aim for a pace that feels like a 6 or 7 out of 10 effort — conversational breathing is gone, but you are not gasping. For the second block (4 rounds), use round 1 as your baseline, then add 1-2 calories or 5-10 meters each successive round, finishing round 4 at roughly 80-85% effort — your hardest push of the day. Technique cues for the ski erg: drive with a big hip hinge first, then pull the arms through — think 'hips, then arms.' Keep the chain taut at the catch and avoid collapsing the chest or rounding the lower back. A common mistake is over-gripping the handles and muscling the pull; let your hips load the movement and the arms finish it. Keep strokes smooth and rhythmic rather than choppy. Record your calories or meters every single interval — this data is your coach during the workout.

Benchmark Notes

Primary limiter is aerobic engine and ski erg-specific pulling efficiency; pacing discipline at 60-70% effort is the secondary factor. L5 (~88 total cals) reflects a solid intermediate CrossFitter averaging roughly 7-8 cals per :45 interval and 10-12 cals per 1:00 interval across all 10 sets, accounting for slight output drop during the final building rounds under accumulated fatigue.

Modality Profile

Ski Erg is a cyclical cardio movement classified as Monostructural (M). It is a machine-based aerobic exercise that does not involve bodyweight gymnastics movements or external weightlifting loads.
