Using daily undulating periodisation — varying load and reps across the week — to manage fatigue and combine qualities in hybrid programmes.
Learning objectives
- Define DUP and compare it with linear periodisation
- Summarise evidence for DUP
- Design DUP weeks for hybrid athletes
- Pair DUP strength days with conditioning
Before this lesson
Why this matters
DUP fits hybrid athletes because it spreads stress and allows flexible pairing with conditioning.
What it is
Varying sets, reps and load across sessions in the same week. In one trial with equated volume, DUP produced greater strength gains than linear periodisation [rhea2002].
Example hybrid week
| Day | Strength | Conditioning |
|---|---|---|
| Mon | Heavy: 5 × 3 @ RIR 1–2 | Easy 30 min |
| Wed | Moderate: 4 × 8 @ RIR 2 | Tempo |
| Fri | Power: 6 × 2 jumps + light lifts | Intervals |
Pair high strength stress with low conditioning stress, and vice versa [haff2016].
Common mistakes and misconceptions
Case study
A tactical athlete with irregular shifts uses DUP: heavy, moderate or light days are chosen based on sleep and schedule. Strength and run times both improve over 12 weeks.
