Wireless. Wearable. Motion-Triggered.

MyoSpark Fit brings electrical muscle stimulation (EMS) into real training and recovery. Use it during dynamic movement, switch to guided routines for focused muscle work, or choose pain relief and recovery sessions when sore muscles need extra attention.

Meet MyoSpark Fit

MyoSpark Fit is a wearable, app-controlled EMS system designed for exercise, recovery, and pain relief. Because the stimulators are worn on the body and controlled from the app, the system can move with you during training instead of being limited to static sessions.

That means you can use motion-triggered stimulation during dynamic exercise, pre-programmed stimulation during focused strength work, and timed recovery routines when your goal is relief or lower-effort activation.

The gap between clinical technology and at-home fitness has officially been closed. The MyoSpark Fit is built to scale with your ambitions.

Truly Wireless Architecture

The system uses Bluetooth to connect the wearable stimulators to your Android or iOS smartphone or tablet. You can seamlessly move between the treadmill, the squat rack, and the recovery mat.

Massive Scalability

You can wirelessly connect up to six MyoSpark stimulators to the app at the same time. Because each stimulator features two channels, you can deliver up to 12 channels of simultaneous stimulation across your entire body for maximum muscle activation.

User-Centered Wearability

The stimulators attach directly to your body using self-adhesive electrodes equipped with magnetic snap connectors.

All-Day Power

The medical-grade rechargeable lithium-polymer batteries provide over six hours of battery life under normal use, ensuring the system outlasts even your longest training sessions.

Smart App Integration

You can easily set your stimulators to fire synchronously (left and right sides at the same time) or in an alternating pattern, and you can save your customized stimulation settings to your profile for quick loading next time.

Why EMS Belongs in Modern Training & Recovery

Good training depends on repetition, effort, timing, and consistency. Electrical muscle stimulation can add targeted muscle activation to that process.

The challenge is not whether EMS can be useful. The challenge is making it simple enough to use during real workouts and easy enough to keep using between workouts.

MyoSpark Fit was built to do exactly that.

MyoSpark Fit uses targeted electrical current to stimulate peripheral nerves, causing your muscles to contract. When used consistently, this stimulation can make your muscles grow and strengthen. Its indications for use include the stimulation of healthy muscles to improve or facilitate muscle performance.

  • Advanced Motion-Responsive Workouts: Every MyoSpark stimulator contains a six-axis inertial measurement unit (IMU). These built-in motion sensors detect your precise movements in real time and automatically adjust the stimulation to match.
  • Dynamic Functional Training: MyoSpark delivers Functional Electrical Stimulation (FES) perfectly in sync with your intentional movements. This motion-triggered stimulation is ideal for active cardiovascular and mobility exercises like cycling, rowing, and walking.
  • Customizable Exercise Routines: For focused muscle building, the app offers timed, pre-programmed stimulation activities that do not require motion sensor feedback. Easily target specific muscle groups with exercises like knee extensions, calf raises, toe raises, hamstring curls, glute bridges, and core stabilization.
  • Precision Control Over Every Rep: The MyoSpark app lets you fine-tune your timed workouts by adjusting the number of sets, reps, and rest periods. You can even customize the exact duration of the stimulation’s ramp-up, hold, and ramp-down phases for each repetition to perfectly match your own tempo.

Motion-Triggered Stimulation for Enhanced Training Sessions

One of the biggest advantages of MyoSpark Fit is motion-triggered stimulation.

During dynamic activities, stimulation can respond to your movement, so muscles are activated at the right time during the exercise. This makes MyoSpark Fit especially well-suited for strength-focused training and hypertrophy-focused EMS sessions, where timing, repetition, and repeatable contractions matter.

For users who want to combine voluntary effort with stimulation, MyoSpark Fit is the best choice for:

  • EMS-assisted cycling
  • Rowing and other repetitive movement training
  • Dynamic lower-body exercise
  • Movement-based muscle activation
  • Strength and hypertrophy-focused workouts that benefit from repeatable stimulation timing

Instead of adding EMS as an afterthought, MyoSpark Fit helps make stimulation part of the movement itself.

Recovery Between Harder Sessions

Recovery should be active, intentional, and easy to repeat.

MyoSpark Fit includes recovery-focused routines that can be used on rest days, after hard workouts, or whenever you want a lower-effort session. Whether you want a short massage-style session, a circulation routine, or isometric stimulation, the system gives you more ways to stay consistent between harder training days.

  • Dedicated Recovery Modes: The MyoSpark mobile app includes a dedicated suite of recovery activities, including massage, circulation, and isometrics.
  • Passive Restoration: These recovery programs are timed activities designed to be used without motion-triggered stimulation. You can simply attach the wearable stimulators, sit back, and let the system do the work while you relax.
  • Boosted Circulation: Even when used at intensities that don’t produce a full muscle contraction, the stimulation can help improve local blood circulation, which is a key component of effective muscle recovery.

MyoSpark Fit can be used for recovery when you want to:

  • Add a lower-effort session between workouts
  • Keep a targeted muscle group engaged without a full training load
  • Build recovery work into your weekly routine
  • Use the same system for both performance work and recovery work

Instead of switching between multiple devices, MyoSpark Fit keeps training and recovery in one platform.

Targeted, Drug-Free Pain Relief

MyoSpark Fit also supports Transcutaneous Electrical Nerve Stimulation (TENS) pain relief sessions for temporary relief of sore and aching muscles from exercise and normal daily activity. By delivering a gentle electrical current, the TENS mode stimulates your nerves to disrupt the pain pathway, reducing your overall perception of pain and leaving you with a soothing, tingling sensation.

That makes it useful when training leaves you with tight calves, sore quads, tired glutes, or an aching lower back. The same system used for exercise can also be used later for relief, helping users stay consistent without adding another device to the routine.

The major advantage: one system for training, recovery, and pain relief.
