The every 1:30 format provides meaningful built-in rest between rounds. Cable flies and scap retracts are light isolation movements with minimal systemic fatigue. Bodyweight squats and lunges at low rep counts (15–16) are very manageable. Only 25 double unders per round adds minimal skill demand. Work time per interval is roughly 50–65 seconds, leaving adequate recovery. Nothing compounds fatigue significantly across 5 rounds.
This workout develops the following fitness attributes:
5 total movements: Cable Chest Fly (Low to High) is Weightlifting (external load/cable machine) = 1W. Air Squat, Double-Under, Lunge, and Single-Under are all Gymnastics (bodyweight movements) = 4G. G: 4/5 = 80%, W: 1/5 = 20%, M: 0%.
| Attribute | Score | Explanation |
|---|---|---|
| Endurance | 4/10 | The EMOM structure with 90-second intervals provides built-in rest, limiting true cardiovascular demand. Jump rope elements add mild aerobic stimulus, but work periods are too short for high endurance stress. |
| Stamina | 6/10 | Moderate rep ranges across 5 rounds each, combining upper body cable work, lower body movements, and jump rope creates cumulative muscular fatigue requiring consistent sustained output throughout both workout blocks. |
| Strength | 3/10 | Cable flys and scapular retractions involve resistance loads but are isolation movements rather than compound strength builders. Squats and lunges are bodyweight, making this more endurance-oriented than strength-focused. |
| Flexibility | 3/10 | Squats and lunges demand moderate hip and ankle mobility. Cable flys require shoulder range of motion through the fly path. Nothing extreme, but consistent full-range movement is necessary throughout. |
| Power | 2/10 | Double unders require brief explosive ankle and calf engagement, but overall movements are controlled and rhythmic. No true power-dominant exercises like cleans, jumps, or sprints are present. |
| Speed | 4/10 | The 90-second window creates mild urgency to complete each couplet/triplet efficiently. Double under cycling and transition speed between movements matter to ensure adequate rest before the next interval. |
