Why This Workout Works
This workout is built around the principles of muscle building training. Use moderate loads (65-80% of your 1RM) with controlled eccentrics and full range of motion. Prioritize progressive overload by adding reps before adding weight. Train each muscle group 2x per week with 10-20 hard sets per muscle per week.
Training Parameters
- Rep Range: 8-12 reps — the hypertrophy sweet spot for maximum muscle growth
- Rest Periods: 60-90 seconds — long enough for quality reps, short enough for metabolic stress
- Sets Per Exercise: 3-4 sets — optimized for muscle building
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.
