Use a swim workout generator to build structured pool sessions for any level. Learn what makes a great generator and how to customize sets, drills, and zones.
Stop copying random sets from the internet. This guide walks through the AquaPlan builder: the 9 training zones, how to design a session, how Garmin FIT and PDF export work, and a sample threshold set you can swim today. Why a Structured Pool Session Beats Improvising Most swimmers write sets on scraps of paper, scroll through Instagram for "inspiration," or do the same 1,500m loop they've done for six years.
That's not training—that's marking time. A structured builder removes the friction between "I should swim more" and actually doing deliberate work. The problem isn't motivation. It's specificity. A 2,000m steady swim hits different than 6x100 @ VO2max, and your body responds differently to each. Without a system, you default to what feels comfortable—which means you plateau.
The AquaPlan builder forces deliberate choices: distance, intensity, rest, stroke variation. AquaPlan gives you a drag-and-drop interface, 9 training zones, and export options that sync directly to Garmin watches. You design the session at your desk. You execute it at the pool. The 9 Training Zones Explained Before you build anything, you need to understand what you're actually prescribing.
AquaPlan uses 9 color-coded zones. Each corresponds to a physiological system and a training adaptation. Here's the condensed version: Most age-group swimmers spend 80%+ of their yardage in GA1 and GA2. That's fine for base fitness. But if you're targeting a 500 free or 200 IM, you need WA work—the kind where your lungs burn and you can't maintain pace past 400m.
Build that ceiling explicitly, don't hope it happens by accident. How to Design a Session in the Builder The interface has three layers: the block palette on the left, the timeline in the middle, and the zone/intensity settings on the right. You drag blocks onto the timeline, adjust the parameters, and watch your session take shape. Here's the step-by-step: If you don't want to build from scratch, browse the library of 130+ plans .
Filter by level (beginner, intermediate, advanced), goal (endurance, speed, technique), or distance (800m, 1500m, 5K). Pick one, customize it, export it. Sample Workout: 1,700m Lactate Threshold Session Here's a real session you can build in the generator right now. Target: aerobic threshold (WA zone), 1,700m total. The key set here is 4x100 @ threshold pace.
If you can hold your target 100 pace across all four reps, you've found your WA zone. If the last rep blows up by 5+ seconds, you went too fast—back off 2-3 seconds per 100 next time. Exporting to Garmin and PDF Building a workout means nothing if you can't execute it properly. The watch is your coach at 5:30 AM when no one's counting your intervals but you.
Garmin FIT export: After building your session, tap Export > Garmin FIT. The file downloads to your device. Open Garmin Connect, sync your watch, and the workout appears in your calendar. Start the session on your watch, and it will announce or display each interval with your target pace range. No more counting tiles, no more guessing. PDF export: Some pools don't allow watches (or you don't want to fumble with it between sets).
The PDF exports a clean, printable workout sheet. Each set is numbered. Distances, intervals, and zones are listed. Tape it to the wall, check off each rep, swim. Take the PDF to the pool for the first week you're trying a new workout. Use Garmin for the second week. Compare: did you hit your intervals more accurately with the watch prompting you, or did the watch create anxiety and throw off your rhythm?
Some swimmers need the nudge. Others swim better blind. Know which type you are. Session Tracking and Progress Every session you complete in the builder logs to your history. Distance, time, zone distribution—AquaPlan tracks it. After 4-6 weeks, you have a dataset. Not feelings about swimming, not "I think I've been doing more." Actual numbers. The achievements system flags milestones: first 5K week, 10 sessions at WA intensity, consistency streaks.
These feel gimmicky until you hit one and realize you've been showing up more than you thought. Momentum compounds. Premium unlocks advanced analytics—weekly volume charts, zone time distribution, pace trends. Free plan gives you the core tracking. For most swimmers, that's enough to see patterns: "I've done zero sprint work in 6 weeks" or "My GA1 volume dropped when I started traveling."
