How to Recover Properly from High-Intensity Intervals

by Answer is Fitness on August 21, 2025      

High-Intensity Interval Training (HIIT) is one of the most effective ways to burn calories, boost cardiovascular fitness, and build strength in a short amount of time. But if you're not recovering properly, you're missing out on some of the biggest benefits — and risking injury, fatigue, or burnout.

At Answer is Fitness in Foxboro, we’re all about training smart. Here’s how you can recover like a pro after your HIIT workouts, whether you’re training in our group fitness classes, with a personal trainer, or on your own.

1. Cool Down, Don’t Just Stop

After those last intense intervals, it might be tempting to collapse on the floor — but don’t skip the cooldown. Spend 5–10 minutes doing light cardio (like walking or cycling at a low pace) to gradually bring your heart rate down. This helps prevent blood pooling and supports muscle recovery.

2. Hydrate Like You Mean It

You sweat hard during HIIT, and that means fluid and electrolyte loss. Replenish with water, and consider adding electrolytes—especially after longer or outdoor sessions. Staying hydrated aids in nutrient transport and helps prevent muscle cramps.

3. Fuel Your Recovery

Post-workout nutrition is key. Aim to eat within 30–60 minutes after your session. A combo of protein (for muscle repair) and carbohydrates (to replenish glycogen) is ideal.

Try:

• A protein shake with a banana
• Grilled chicken with sweet potatoes
• Greek yogurt with berries and granola

Ask one of our trainers or nutrition coaches if you need personalized meal ideas!

4. Stretch and Foam Roll

HIIT causes microtears in muscle tissue—which is a good thing when paired with recovery. Static stretching and foam rolling can reduce soreness and improve flexibility. If you're not sure where to start, join a stretch class or recovery session here at Answer is Fitness.

5. Don’t Skip Rest Days

Recovery happens outside the gym, too. Give your muscles time to rebuild with proper sleep and rest days. We recommend at least one full rest day per week if you're doing HIIT regularly. Not sure how often to train? Our team can build a custom plan that fits your goals and lifestyle.

6. Try Active Recovery

On your off days, light movement like walking, yoga, or a leisurely bike ride can boost circulation without overtaxing your body. We even offer active recovery classes and mobility workshops at our Foxboro location — check our schedule to join!
