Here's how Firefly works

Firefly uses OnPulse™ technology to kickstart your body’s natural recovery process to speed up your recovery and reduce soreness.

Firefly stimulates blood flow

 

Firefly stimulates your peroneal nerve, triggering muscle contractions and setting the foundation for enhanced recovery.

Increased blood flow helps improve recovery

 

Leg contractions increase blood flow throughout your whole body, delivering the essential recovery fuel to your muscles.

Get back to training, faster

 

Increased blood flow flushes out lactic acid and delivers vital nutrients, paving the way for a rapid and effective recovery.

Frequently Asked Questions

How does Firefly work?

Firefly's OnPulse™ technology uses small electrical pulses to stimulate the peroneal nerve (a nerve in your leg). This increases full-body blood flow. That means more fresh blood and oxygen to reduce lactic acid and soreness, eliminate toxins, and keep muscles flexible.

When and how long should I wear the Firefly devices?

Recommended usage will optimize recovery so you can train harder and perform better. Firefly Recovery is used for warm up (30-60 minutes) post workout recovery (1-4 hours) and travel (duration of travel).

Should I use Firefly during training or working out?

No, it is not recommended to use Firefly during training or a workout. However, as Firefly is a portable device, it can be used when walking, stretching or on-the-go.

Can I use Firefly for upper body recovery?

Absolutely. Since Firefly increases blood flow throughout your entire body, it always functions as a full-body recovery device.

Why should I get a Starter Pack?

Firefly Starter Packs have everything you need to get the full Firefly experience - they also comes at a discounted price.

Starter Packs include Firefly devices, and two knee straps.

How many Firefly devices do I need?

If you're new to Firefly, we reccomend getting a Starter Pack, which has Firefly devices and knee straps. This gives you enough time to get the full recovery experience.

If you're restocking, you can save money by buying in bulk or getting a subscription.

Do I need the knee strap?

We reccomend getting the Knee Straps (included in the Starter Packs).

The Knee Strap keeps Firefly securely in place whether you are resting or in motion. Additionally, as the gel-based backing on Firefly devices may become less adhesive after multiple uses, the knee strap will help to ensure proper stimulation from the device.

How do I use Firefly?

Recommended usage will optimize recovery so you can train harder and perform better.

Firefly Recovery is used for warm up (30-60 minutes), post workout recovery (2-4 hours), and travel (duration of travel).

Simply apply Firefly to the correct location on your peroneal nerve and turn the device on.

How long does Firefly last?

When used as recommended, the Firefly device has a 30 hour battery life. The number of uses will depend on the length of each recovery session (average session is 1-4 hours). Afterwards, the battery is not rechargeable, it can be removed and recycled like any household battery.

Is the Firefly device painful to use?

The Firefly device should not be painful. You will feel muscles in the lower leg contract every second, which causes your foot to twitch (Firefly flutter). It may take a few moments to adjust to the sensation, but the movement is critical to increasing blood flow and recovery. if the sensation is too strong, decrease the level.

How does Firefly differ from muscle stim?

The Firefly is a modified NMES that stimulates a nerve vs. a muscle, it is not a muscle stim or TENS unit. Stimulating the peroneal nerve causes muscles to contract and to increase blood flow. Stimulating a muscle (with traditional NMES) for extended periods of time can cause muscle fatigue. The Firefly safely avoids muscle fatigue that can be caused by TENS.

Who should not use the Firefly device?

Individuals with pacemakers and recently diagnosed DVT should not use the Firefly. See the instructions that accompany the device for a full list of contraindications, warnings and precautions. Please see our technical specifications.
