Sweet spot training plan

The time-efficient way to build FTP and muscular endurance when your hours are limited.

8 weeksTime-crunched riders with 4 to 8 hours a week who want to raise FTP and sustainable power.

Overview

Sweet spot sits at roughly 88 to 94% of FTP. It is hard enough to drive real adaptation, but sustainable enough that you can rack up a lot of quality minutes without the deep fatigue of full threshold work. That balance is why it gives so much fitness per hour.

This 8-week block adds a bit more time at sweet spot each week. Start around 3x10 to 12 minutes and build toward longer intervals, with a recovery week so you adapt rather than dig a hole. Two to three sessions a week, wrapped in easy endurance, is the proven recipe.

How the plan is structured

Introduce
Weeks 1-3
Build the habit: 3x10 to 12 min at 88-94% FTP, twice a week.
Build
Weeks 4-6
Longer intervals (3x15 up to 2x20) and a third weekly session.
Peak and recover
Weeks 7-8
Peak volume, then back off to absorb the work.

Key workouts

Sweet spot progression
Week 1 3x10, week 2 3x12, week 3 3x15, week 4 2x20, then repeat a little harder.
Over-unders
3 sets of 3 min at 90% then 1 min at 100% FTP, to bridge sweet spot into threshold.
Endurance with SS blocks
A longer zone-2 ride with 2 to 3 sets of 15 min sweet spot embedded, for extra time at intensity.

Tips to get it right

  • Two to three sweet spot sessions a week is enough. More just adds fatigue without more gains.
  • Keep easy days genuinely easy. The intensity only works if you recover between sessions.
  • Progress by adding minutes, not by riding each interval harder.

Frequently asked questions

How much sweet spot training should I do per week?

Two to three sessions a week suits most riders, with beginners starting at one or two. Fill the rest of the week with easy endurance so you recover and adapt.

How much can sweet spot training raise my FTP?

Over a structured block most consistent riders see a clear FTP increase. Gains are largest for newer or detrained riders and slower for the well-trained.

Sweet spot or threshold training?

Sweet spot gives more quality minutes with less fatigue, which is ideal on limited hours. Threshold is more specific but costlier. A good plan builds sweet spot first, then adds threshold. See the FTP plan.
