How to Structure a Professional Swimming Workout
Swimer Team
International swimming coaches and high-performance technicians with 40+ years of combined experience.
Quick summary: A professional session has 5 blocks: warm-up (400-800m), technique (200-400m), main set (800-1,800m), supplementary (200-600m) and cool-down (100-300m). This structure maximizes every minute in the water.
The structure of a swimming workout is what separates a productive session from just "swimming laps." A well-organized workout maximizes every minute in the water, trains all necessary qualities and prevents injuries.
The 5 parts of a professional session
| Block | Duration | % of session | Objective |
|---|---|---|---|
| Warm-up | 400-800m | 15-20% | Cardiovascular and muscular activation |
| Technique | 200-400m | 10-15% | Improve efficiency |
| Main set | 800-1,800m | 40-50% | Primary physiological stimulus |
| Supplementary | 200-600m | 10-20% | Additional volume, kick/pull |
| Cool-down | 100-300m | 5-10% | Recovery, decompression |
1. Warm-up (400-800m)
Objective: activate the cardiovascular system and prepare muscles. Includes easy swimming varying strokes, kick with board and progressive sets. Never start with the main set directly — cold muscles perform worse and are more prone to injury.
Example: 400m (100 free easy + 100 backstroke + 100 free progressive + 100 kick)
2. Technique block (200-400m)
Technical drill sets to improve swimming efficiency. This block comes before the main set because technique is best learned without fatigue. Under fatigue, your body falls back on established patterns — not the new ones you're trying to learn.
Example: 4×75m (25 catch-up + 25 fist drill + 25 full stroke) with 15"
3. Main set (800-1,800m)
The heart of the workout. This is where intensity zones are applied based on the session's objective: endurance (A1-A2), threshold (A3-TH) or speed (VO₂-LAC). Exact paces come from your CSS.
4. Supplementary (200-600m)
Kick work, pull buoy sets, secondary strokes or sets with fins. Adds aerobic volume without the main set's load and works specific aspects like kick or upper body.
5. Cool-down (100-300m)
Easy swimming, dynamic stretching in the water and decompression. Gradually lowers heart rate and promotes recovery for the next session.
Complete session examples
Endurance session (3,000m)
- Warm-up: 400m (100 free + 100 backstroke + 100 free + 100 kick)
- Technique: 4×75m drills with 15" = 300m
- Main set: 5×300m free A3 with 25" = 1,500m
- Supplementary: 4×100m kick with board A2 with 15" = 400m
- Supplementary 2: 4×50m pull buoy A1 with 10" = 200m
- Cool-down: 200m easy mixed
Speed session (2,500m)
- Warm-up: 600m (200 free + 200 backstroke + 200 progressive)
- Technique: 4×50m drills with 15" = 200m
- Main set: 8×100m VO₂ with 30" = 800m
- Supplementary: 12×25m sprint with 45" = 300m
- Supplementary 2: 4×100m IM A1 with 20" = 400m
- Cool-down: 200m easy

Step by step
- 1
Warm-up (400-800m)
Swim 10-15 minutes progressively: start very easy and increase intensity. Include at least 100m kick and 100m of a different stroke. Never start the main set without warming up.
- 2
Technique block (200-400m)
Do 2-3 specific drills for your level. After warm-up and before the main set, when the body is activated but not fatigued. This is when technique is best learned.
- 3
Main set (800-1,800m)
The highest intensity and volume block. Defines the session's objective (aerobic, threshold, speed). Use paces based on your CSS and respect prescribed rest intervals.
- 4
Supplementary (200-600m)
Lower intensity sets working secondary qualities: kick, other strokes, pull or equipment drills. Maintains volume without overloading.
- 5
Cool-down (100-300m)
Swim at very easy pace (A1 zone) for 5-8 minutes. Facilitates lactate clearance, lowers heart rate and prevents post-workout muscle stiffness.
