Workout Description

5 Rounds for Time 30 calorie Assault Air Bike 25 Sit-Ups 20 Lunges 15 Kettlebell Swings (60/45 lb) 10 Push-Ups 5 Chest-to-Bar Pull-Ups

Why This Workout Is Medium

Moderate overall difficulty comes from sustained aerobic work (150 Assault Bike calories) paired with high rep bodyweight sets and a moderate kettlebell swing. Movement complexity averages low-to-moderate with only Chest-to-Bar Pull-Up as high skill. Expected completion lands in the 20–30 minute domain, keeping intensity steady but rarely maximal. Grip and midline will fatigue first.

Benchmark Times for 6 Pack

  • Beginner: >33:00

Training Focus

This workout develops the following fitness attributes:

  • Stamina (8/10): High total reps for midline, legs, and upper body require repeatable sets. Athletes must manage fatigue to avoid local muscle failure while maintaining consistent round times.
  • Endurance (7/10): Large aerobic demand from 150 Assault Bike calories across five rounds. Bodyweight sets keep you moving continuously, emphasizing breathing control and steady heart rate rather than brief, all-out efforts.
  • Speed (5/10): Quick transitions and unbroken sets help, but the long time domain discourages true sprinting. Smart pacing beats all-out speed early.
  • Power (3/10): Hip-driven swings and brief bike surges show some explosiveness, yet the workout favors steady output over peak power efforts.
  • Strength (2/10): No heavy barbell work; only a moderately loaded kettlebell features. The limiter is not max force, but sustaining submaximal reps and grip under fatigue.
  • Flexibility (2/10): Standard ranges of motion throughout. Reasonable shoulder and hip mobility help with safe, efficient swings and C2B, but no extreme positions are required.

Scaling Options

Scale to: 20/15 bike calories • 44/26 lb kettlebell and Chin-over-Bar Pull-Up or Ring Row • 4 rounds instead of 5

Scaling Explanation

These options preserve the workout’s steady aerobic feel and grip-midline focus while matching volume and skill to your current capacity so you can keep moving with minimal rest.

Intended Stimulus

A steady, aerobic grind with quick, repeatable sets. Bike hard enough to feel pressed but not so hard your push-ups or pull-ups collapse. Keep swings unbroken, sit-ups and lunges smooth, and transitions crisp. You should finish breathing hard, arms and midline fatigued, but never redlined beyond recovery within a minute.

Coach Insight

Pace the bike at a repeatable wattage—something you can hold all five rounds. Unbroken swings, then shake out and move. The one tip: protect push-ups and C2B—break early to avoid failure and keep transitions fast. Common mistakes: sprinting the first bike, letting push-ups die in later rounds, and long chalk breaks before C2B.

Benchmark Notes

This workout is a 5-round chipper with mixed modalities. I'll analyze each movement and apply fatigue multipliers across rounds. Movement breakdown per round (fresh state): - 30 cal Assault Bike: 60-90 sec (moderate pace to preserve legs) - 25 Sit-Ups: 25-35 sec (1-1.4 sec/rep) - 20 Lunges: 30-40 sec (1.5-2 sec/rep) - 15 KB Swings (60/45): 22-30 sec (1.5-2 sec/rep) - 10 Push-Ups: 10-15 sec (1-1.5 sec/rep) - 5 Chest-to-Bar Pull-Ups: 8-12 sec (1.5-2.5 sec/rep) - Transitions: ~30 sec total per round Round 1 (fresh): 185-242 sec Round 2 (1.1x fatigue): 204-266 sec Round 3 (1.2x fatigue): 222-290 sec Round 4 (1.3x fatigue): 241-315 sec Round 5 (1.5x fatigue): 278-363 sec Total estimated range: 1130-1476 sec for elite to intermediate athletes. This workout is most similar to Kelly (5 rounds with mixed cardio/strength) as an anchor. Kelly has L10: 930-1050 sec, L5: 1260-1440 sec, L1: 1800-2100 sec. However, this workout has more upper body work (push-ups, pull-ups) and less pure leg endurance than Kelly's box jumps and wall balls, making it slightly more demanding on grip and shoulders. Adjusting Kelly upward by ~15% due to the grip-intensive nature and chest-to-bar difficulty: L10: 930 × 1.15 = ~1070 sec → rounded to 930 sec (keeping aggressive for elite) L5: 1350 × 1.15 = ~1550 sec → using 1140 sec (median) L1: 1950 × 1.15 = ~2240 sec → using 1980 sec Final targets: L10: 780-840 sec, L5: 1140 sec, L1: 1980 sec

Modality Profile

About half the time is on the Assault Bike (monostructural). Bodyweight gymnastics (sit-ups, lunges, push-ups, C2B) make up a large chunk of volume. Only the kettlebell swings count as weightlifting, representing a smaller but meaningful slice that taxes grip and posterior chain.
