Form cues
- Position a bench inside the Smith machine and sit with your upper back against it.
- Unlock the bar at hip level and lower your hips toward the floor.

Form cues

Why This Workout Works
This workout is built around the principles of endurance training. Use lighter loads (40-60% 1RM) with high reps. Minimize rest between sets to challenge your cardiovascular system. Circuit training and supersets are particularly effective. Focus on maintaining form even as fatigue accumulates.
Training Parameters
- Rep Range: 15-25 reps — designed for sustained muscular effort
- Rest Periods: 30-45 seconds — short rest to maximize calorie burn
- Sets Per Exercise: 2-3 sets — optimized for endurance
Abs Training Tips
- *Heavy compound lifts train your abs hard — dedicated ab work is the finishing touch, not the foundation.
- *Anti-rotation and anti-extension exercises (pallof press, ab wheel) build real functional core strength.
- *Visible abs are made in the kitchen — no amount of crunches overcomes a caloric surplus.
