Forty-five minutes gives you room for a proper workout. Enough for a warm-up, a solid main set, and a cool-down — about 2,000–2,500m depending on your pace. Here are three sessions for different goals.
Session 1: Threshold Endurance
Goal: Raise your sustainable pace. Total: ~2,200m
- 400m easy warm-up
- 4×50m build, :15 rest
- Main set: 10×100m on 2:00, target your threshold pace
- 400m easy cool-down
Key instruction: Hold even splits throughout. The last 100m should be within 3–4 seconds of the first.
Session 2: Speed Development
Goal: Build raw speed and fast-twitch power. Total: ~2,000m
- 400m easy warm-up
- 4×50m as 25m drill + 25m sprint, :20 rest
- Main set A: 6×50m at 90% effort, :30 rest (really push these)
- 300m easy
- Main set B: 6×25m all-out sprint, :45 rest (maximum speed)
- 300m easy cool-down
Key instruction: Rest fully between sprints. Speed work only works if you’re recovered enough to actually go fast.
Session 3: Mixed Stroke
Goal: Cross-train all four strokes, build overall fitness. Total: ~2,000m
- 300m easy freestyle warm-up
- Drill set: 4×100m IM order (butterfly, backstroke, breaststroke, freestyle), :30 rest
- 200m easy
- Main set: 8×75m as 25m back + 25m breast + 25m free, :20 rest
- 200m easy freestyle cool-down
Key instruction: Focus on stroke quality, not pace. Mixed stroke sessions are excellent for identifying which strokes need the most work.
Making the Most of 45 Minutes
Start warming up immediately. Get in the water and start moving within 2 minutes of entering. Every minute spent adjusting goggles at the wall is a minute not swimming.
Know your set before you arrive. Have your workout planned so there’s no thinking time between sets. SwimBeat lets you build your set in advance on your phone — open it at the pool and execute.
Skip the extended warm-up. For 45-minute sessions, 400m warm-up is plenty. Your body is warm well before 800m.
