Training Rules
10 rules (2 hard, 8 soft)
Evidence-based constraints that guide workout generation. Hard rules are never broken; soft rules can be adjusted for experienced athletes.
Volume
Aim for 12-20 sets per muscle group per week
Research shows volume is the primary driver of hypertrophy
Intensity
Train to 0-2 RIR (reps in reserve) on working sets
Training close to failure maximizes motor unit recruitment
Maximum 4 high-volume training sessions per week
Hypertrophy requires higher volume but recovery is still essential
Exception: Experienced lifters with established recovery capacity
Technique
Control the eccentric (lowering) phase - 2-3 seconds minimum
Time under tension and eccentric loading drive muscle damage
Focus on feeling the target muscle work, not just moving weight
Mind-muscle connection improves muscle activation
Use full range of motion unless specifically targeting partials
Full ROM maximizes mechanical tension and stretch-mediated hypertrophy
Compound movements before isolation within each muscle group
Compounds allow heavier loads; do them fresh
Safety
Progressive warm-up sets before working weight
Prevents injury and improves performance
Recovery
Deload every 4-6 weeks - reduce volume by 50%
Accumulated fatigue masks fitness; deloads allow adaptation
Lifestyle
Adequate protein (1.6-2.2g/kg) and caloric surplus/maintenance required
Muscle can't grow without building blocks and energy
