Training Rules
9 rules (5 hard, 4 soft)
Evidence-based constraints that guide workout generation. Hard rules are never broken; soft rules can be adjusted for experienced athletes.
Technique
Every session must include dedicated technique/drill work
Swimming efficiency is technique-dependent; continuous reinforcement required
Exception: Race simulation or test sets
Minimum 20% of session should be drills for technique improvers
Drilling ingrains correct movement patterns
Exception: Advanced swimmers with established technique
Volume
Track volume in meters/yards, not time
Distance is the meaningful metric; same time can mean very different workloads
Weekly volume increase should not exceed 10%
Shoulder overuse is the primary swimming injury
Exception: Returning from planned rest
Safety
No high-intensity work without 400m+ warmup
Shoulders are vulnerable; warmup prevents injury
Recovery
Include non-freestyle strokes for shoulder balance
Varied strokes prevent overuse patterns
Exception: Triathlon-specific blocks
Intensity
Sprint sets require full recovery (1:3 to 1:4 work:rest ratio)
Incomplete recovery compromises power and technique
CSS (Critical Swim Speed) test every 4-6 weeks during build
Threshold changes; zones should be updated
Exception: Maintenance phase
Maximum 4 quality sessions (threshold/sprint sets) per week
Swimming is lower impact but shoulder stress accumulates
Exception: Peak phase, experienced swimmers only
