WHO'S THIS FOR
Who is AquaBoard for?
AquaBoard publishes structured swim workouts five days a week for three levels of swimmer. Every set is written by a biomedical engineer with competitive swimming experience, and programming is informed by research in exercise physiology and motor learning. This is not a training app or a coaching service. It is a set of workouts, published on a consistent schedule, organized into eight-week training blocks, and designed to help you improve whether you are training for fitness, a sprint meet, a triathlon, or an open water race.
Beginner: Rest-based sets
Beginner workouts use fixed rest intervals (measured in seconds of rest between repetitions) rather than pace-based send-offs. This approach removes the pressure of the pace clock and allows newer swimmers to focus on building aerobic capacity and developing efficient stroke mechanics.
Sets are primarily freestyle with occasional backstroke and choice stroke. Volume starts moderate and increases gradually across the eight-week block. A swimmer who completes a full Beginner block will have the endurance and comfort level to begin Intermediate training.
Who this level is for:
- Swimmers returning to the pool after time away
- Fitness swimmers looking for daily structure
- Triathletes building swim volume for the first time
- Open water swimmers working on base endurance
- Anyone who can swim 50 meters of freestyle without stopping
A typical set
WU 300 however you like (12 min)
DRILL 8 x 25s with 30 sec rest, 5 Kick Switch FR (10 min)
One arm out, ear on shoulder, one eye in
the water one eye out. Switch every 5 kicks.
DRILL 8 x 25s with 30 sec rest, 3 Kick Switch FR (10 min)
Same thing but switch every 3 kicks
MAIN 16 x 25s with 25 sec rest, Freestyle (20 min)
Build 1-3 from 50% to 90%, sprint the 4th
4 rounds of this for 16 total
CD 200 easy, work on breathing position
Intermediate: Interval training
Intermediate workouts introduce pace-based intervals with send-offs. Sets incorporate all four competitive strokes and are structured around aerobic and threshold intensities.
The eight-week block follows a standard periodization model: early weeks build volume at moderate intensity, middle weeks increase pace demands and reduce rest, and the final weeks taper volume while maintaining intensity. This level works equally well for a masters swimmer preparing for a meet and a triathlete trying to lower their 1500m split.
Who this level is for:
- Masters swimmers training for meets
- Triathletes and open water swimmers with an established swim base
- Former competitive swimmers who want structured training again
- Anyone preparing for events from a 200 to a 5K open water swim
- Swimmers who have completed a Beginner block or equivalent
A typical set
WU 600 (300 Free, 200 IM, 100 Kick)
PRE 16 x 50s on 1:00
4 sprint drill, 4 build 50% to 90%
4 at 85%, 4 breathe every 5
MAIN 8 x 100s with 15 sec rest, mile pace
2 min rest
6 x 100s with 15 sec rest, hold stroke count
2 min rest
6 x 100s with 15 sec rest, fight for it
FIN 12 x 25s on :45 primary stroke, all out
Advanced: Race-pace training
Advanced workouts use short repetitions performed at your target race velocity with fixed rest intervals, typically 15 to 20 seconds. Research in exercise physiology has shown that this short work-to-rest format allows athletes to sustain high-quality effort for longer without the fatigue accumulation that comes with traditional long-interval sets. Separately, research in biomechanics has demonstrated that stroke technique is specific to the speed at which you swim, which means training at your goal pace develops the exact motor pattern you need on race day.
This is not a sprinters-only method. Your target pace is your target pace, whatever the event. A 1500m freestyle swimmer uses 1500m race pace. A triathlete preparing for a 1.2-mile swim leg uses that pace. The distances are short but the velocity matches your goal, and that is what makes the training specific.
Sets use a failure-based progression: when you can no longer hold target pace, you rest one repetition and re-enter the set. The set ends after three total failures. This gives you a built-in, objective way to measure improvement from week to week.
AquaBoard's Advanced programming draws on this body of research but is not a strict copy of any single published protocol. Sets reflect the author's own experience and judgment alongside these principles.
Who this level is for:
- Competitive pool swimmers training for specific events at any distance
- Distance swimmers and open water racers who want pace-specific training
- Triathletes looking to sharpen their swim leg
- Experienced swimmers interested in race-pace methodology
- Swimmers who have completed an Intermediate block and are comfortable holding pace on a clock
A typical set

A note on the science
AquaBoard's programming is informed by published research in exercise physiology and motor learning. The short work-to-rest format used in Advanced sets draws on findings first demonstrated by Astrand and colleagues in Sweden in the 1960s, which showed that short intervals at high intensity produce significantly less lactate accumulation and glycogen depletion than longer intervals at the same workload. The emphasis on training at race-specific velocity reflects research by Craig, Pendergast, Toussaint, and others showing that stroke mechanics and neuromuscular patterns change with swimming speed, making pace-specific practice essential for competition readiness.
The periodization structure across all three levels draws on established principles of progressive overload, supercompensation, and taper that are standard in endurance sport programming.
