How Often Should You Do Interval Training?
by Answer is Fitness on August 16, 2026
Interval training can be an effective way to add variety and challenge to your fitness routine. However, doing more intervals isn’t always better. Your ideal frequency depends on your fitness level, workout intensity, and how well your body recovers.
Start With 1–2 Sessions Per Week
For many people, one or two interval-training sessions per week is a reasonable starting point. This gives you time to recover while still allowing you to build consistency. Beginners may want to start with shorter intervals and longer recovery periods before gradually increasing the challenge.
Pay Attention to Recovery
Interval workouts can be demanding, especially when they involve higher-intensity efforts. Give yourself adequate recovery between challenging sessions and avoid stacking hard workouts on consecutive days. Easy movement, rest days, and other forms of lower-intensity exercise can help create a balanced routine.
Adjust as Your Fitness Improves
As you become more comfortable with interval training, you can gradually adjust the duration, intensity, or number of intervals. Your routine should still include a mix of activities rather than relying exclusively on high-intensity workouts.
Build a Balanced Fitness Routine
Interval training works best as part of an overall fitness plan that includes cardiovascular activity, strength training, mobility work, and recovery. If you're unsure how often to include intervals or how to structure your workouts, a fitness professional can help you choose an approach that fits your current fitness level and goals.
