⏱️ Interval Recovery Ratio Calculator
Use this to compare work and rest inside interval sessions. It is a simple way to see whether a workout is built for speed, threshold, or just surviving the session.
Calculator
1:1 for balanced efforts | 1:2 or 1:3 for speed work | 2:1 or tighter for hard threshold work
Why This Matters
Interval ratios shape the whole feel of a workout. A 1:3 session is very different from a 2:1 session, even if both sound like interval training.
When you track the ratio on purpose, you stop guessing whether a session is actually built for speed, threshold, or toughness.

How FitnessView Helps
FitnessView gives you the workout history and heart rate response to see whether the ratio is doing what you wanted.
That makes planning the next interval block a lot easier.
Tips
- Use seconds for short intervals so the math stays accurate.
- If the rest interval is too short, the next rep often turns into junk miles.
- Match the ratio to your goal instead of copying whatever looks hard.
- Track how interval sessions affect your next-day readiness in FitnessView.
Frequently Asked Questions
Is a tighter ratio always better?
No. The best ratio depends on the goal. Shorter rest is not automatically smarter.
Can this help with running workouts?
Absolutely. It works for running, cycling, rowing, and any other interval-based training.
Do I need perfect precision?
Not perfect, just consistent. Keep the same unit and the ratio will be useful.
