Creating a Weekly Turbo Training Plan (Coach's Guide)
The short answer
- A solid weekly turbo plan needs 3 to 4 quality structured sessions plus rest: most amateurs improve fastest on 2 hard days, 1 to 2 easy days, and 1 full rest day.
- Polarised training keeps most of your riding easy and a small slice very hard. Sweet-spot packs more time-effective intensity into the middle. Both work, so pick the one that fits your hours.
- Time-crunched riders with under 5 hours a week should lean sweet-spot. Riders with 6 hours or more, or anyone feeling cooked, should lean polarised.
- Always anchor the plan to your FTP, leave at least one easy day between hard sessions, and build in a recovery week every fourth week.
If you want a weekly turbo training plan that actually moves the needle, build it around three or four quality sessions and real rest, not seven days of hammering. The simplest version that works for most amateurs is two hard structured sessions, one or two easy endurance rides, and at least one full rest day, all anchored to your FTP. Whether you choose a polarised or a sweet-spot approach comes down to how many hours you genuinely have each week.
After writing weekly plans for riders for years, I have learned that the week that gets ridden beats the perfect week that gets skipped. Below is exactly how I structure a week, when I reach for polarised versus sweet-spot, and a sample week you can lift straight onto your trainer.
What a good weekly turbo plan looks like
A weekly plan is not a random pile of workouts. It is a balance of stress and recovery that nudges your fitness up week on week without breaking you. Three things matter more than anything else:
- Hard days are genuinely hard. When a session is meant to be intense, you ride it at the right power, not at “a bit uncomfortable”.
- Easy days are genuinely easy. This is where most riders go wrong. Easy means you can hold a conversation, around 56 to 75 percent of FTP.
- Rest is part of the plan. Adaptation happens when you recover, not when you ride. At least one full day off every week is non-negotiable for most people.
Before you build anything, you need your zones. Those come from your FTP, so if you have not tested recently, start there. My guide on understanding training zones on the turbo walks through each zone and what it feels like, and understanding power readings on your turbo trainer covers how to read and trust the numbers on screen.
Polarised vs sweet-spot: which model should you use?
This is the question I get asked most. Both are proven, and the honest answer is that the right one depends on your available hours and how you respond to intensity.
Polarised training keeps roughly 80 percent of your riding easy (Zone 1 to 2) and the remaining 20 percent very hard (Zone 4 to 5), with very little in the middle. It is forgiving, it builds a deep aerobic base, and it is hard to overcook because most of the week is gentle. The catch: it needs volume to work, so you really want 6 hours a week or more.
Sweet-spot training lives in the middle, around 88 to 94 percent of FTP, just below threshold. It is the most time-efficient way to build sustainable power, which is why it suits indoor riders so well. You get a lot of training benefit per minute. The catch: it is taxing, so you cannot do it every day, and stacking too much sweet-spot leads to flat legs and stale form.
| Factor | Polarised | Sweet-spot |
|---|---|---|
| Weekly hours suited to | 6+ hours | Under 5 hours |
| Intensity spread | 80% easy / 20% very hard | Lots of moderate-hard |
| Main benefit | Aerobic base, durability | Time-efficient FTP gains |
| Burnout risk | Lower | Higher if overdone |
| Best for | Endurance riders, base season | Time-crunched riders, build phase |
In practice I rarely run a rider on one model all year. I use sweet-spot through the dark winter months when time is tight, then shift towards a more polarised shape as the days lengthen and outdoor volume returns. If you only ever do one, and you are short on time, sweet-spot wins for indoor training.
How to build your week, step by step
Here is the order I work through with every rider. Follow it and you will end up with a plan that fits your life rather than fighting it.
- Count your honest hours. Not the hours you wish you had. If it is realistically four 60-minute slots, build for that. A plan you actually complete beats a perfect plan you skip.
- Fix your rest day first. Pick the day you are most likely to be busy or tired and protect it as full rest. Everything else fits around it.
- Place your two hard sessions. Space them so there is at least one easy or rest day between them. Tuesday and Thursday, or Tuesday and Saturday, work well for most.
- Fill the gaps with easy riding. Add one or two endurance or recovery spins. These are not optional filler: they are where aerobic fitness is built.
- Choose your model. Apply polarised or sweet-spot shaping to the hard days based on the table above.
- Plan a recovery week. Every fourth week, cut total intensity and volume by roughly 40 to 50 percent so your body absorbs the work.
Sample weekly turbo plan
Here is a balanced 5-day week for a rider with around 5 to 6 hours, using a sweet-spot lean with one polarised-style hard day. Adjust the durations to your level and your FTP.
| Day | Session | Focus | Time |
|---|---|---|---|
| Monday | Rest | Full recovery | 0 |
| Tuesday | Sweet-spot 3 x 12 min @ 90% FTP | Sustainable power | 60 min |
| Wednesday | Easy endurance Zone 2 | Aerobic base | 45 to 60 min |
| Thursday | VO2 max 5 x 3 min @ 110-120% FTP | Top-end power | 60 min |
| Friday | Rest or gentle spin | Recovery | 0 to 30 min |
| Saturday | Long Zone 2 with 2 x 20 min tempo | Endurance + durability | 75 to 90 min |
| Sunday | Easy recovery spin | Active recovery | 30 to 45 min |
That is two quality sessions (Tuesday sweet-spot, Thursday VO2), genuine endurance on Saturday, easy filler around them, and a protected rest day. If you only have three or four slots, drop the Sunday spin and shorten Saturday first, then keep both quality days.
If you are newer to indoor training, do not start here. Build up to it. My guides on how long beginner turbo trainer sessions should be and how often beginners should use a turbo trainer will keep your early weeks sensible so you actually stick with it.
Structuring each individual session
Every session in the week, hard or easy, follows the same skeleton: warm-up, main set, cool-down. A good warm-up matters even more indoors because you do not have the rolling start of a road ride. I cover the full template in how to structure a basic turbo training session, and if you want to understand why those punchy short efforts on hard days work, why short intervals on a turbo trainer explains the physiology.
A smart trainer in ERG mode makes structured weeks far easier because it holds each target for you, so you can focus on cadence and breathing rather than chasing a number. If you are still on a basic trainer and weighing an upgrade, my best smart turbo trainers for Zwift roundup is where I would start, and the direct drive vs wheel-on comparison explains what you actually gain.
How to progress the plan over time
A weekly plan is a template, not a fixed thing. Progress it gradually:
- Add load slowly. Increase total weekly time or intensity by no more than around 10 percent week to week.
- Use the recovery week. Every fourth week, back off. You will come back stronger, not weaker.
- Retest and rebuild zones. Every 6 to 8 weeks, retest FTP and rebuild every target around the new number.
- Listen to the signals. Persistent flat legs, poor sleep or a rising resting heart rate mean you need more rest, not more sessions.
The bottom line
Keep it simple: two genuinely hard sessions, one or two genuinely easy rides, a protected rest day, and a recovery week every fourth week, all built on your current FTP. Choose sweet-spot if you are short on time and polarised if you have the hours, and do not be afraid to mix the two across a season. The best weekly plan is the one you will actually finish, week after week. That consistency, far more than any clever workout, is what makes you faster.
