WHOOP Bicep Band – Compatible with 5.0/MG – Not Compatible

The WHOOP Bicep Band (L/XL) is a CoreKnit, jet-black armband designed to hold your WHOOP 5.0 or WHOOP MG securely on your upper arm for comfortable 24/7 tracking while freeing your wrist.

If you want continuous performance, sleep, and recovery data without wearing a device on your wrist, the WHOOP Bicep Band offers a soft, stretch-knit solution built for daily use and intense training. Sized L/XL, this version fits larger arms and uses WHOOP’s Fast Link adjustment to get a snug, stable placement. It is specifically made for WHOOP 5.0 and WHOOP MG devices and is not compatible with WHOOP Generation 4.0 hardware.

How does the bicep placement affect data collection?

Moving your WHOOP sensor from the wrist to the bicep keeps continuous heart-rate and motion tracking while reducing interference from wrist movement. Placement on the upper arm can improve comfort for people who wear watches or bracelets and offers a discreet option for workplace or performance environments.

• Maintains 24/7 recording of activity, sleep, and recovery metrics
• Reduces wrist noise when lifting or during repetitive hand work
• Secure, close contact with skin for reliable sensor readings

What makes the CoreKnit design suitable for long wear?

CoreKnit fabric combines stretch and breathability so the band stays comfortable through workouts, sleep, and all-day wear. The knit is engineered to resist wear while conforming to the arm, which helps prevent chafing and keeps the sensor stable.

• Soft, stretch-knit material that adapts to arm movement
• Durable construction for repeated use and sweat exposure
• Low-profile, lightweight feel that minimizes distraction

How do I size and adjust the L/XL band correctly?

The L/XL size is intended for larger arm circumferences and includes the Fast Link adjustment system to fine-tune tightness. For best results, position the band on the thickest part of your bicep and tighten until the sensor sits flat against skin without causing discomfort.

• Available in L/XL for larger arms; S/M sold separately
• Fast Link lets you tighten or loosen quickly and securely
• Adjust so the WHOOP sits flush and does not slide during motion

Will the band work with all WHOOP features I use now?

The bicep band supports full WHOOP data capture for activity, sleep, and recovery while compatible with WHOOP Life features; however, ECG readings must be taken using a wrist-worn accessory. Also note this band is not compatible with Generation 4.0 hardware.

• Full support for continuous tracking with WHOOP 5.0 and WHOOP MG
• Use with WHOOP Life—ECG still requires a wrist device
• Not suitable for WHOOP Gen 4.0 devices

Who is this for? The WHOOP Bicep Band L/XL is tailored for larger athletes, fitness enthusiasts, and professionals who want reliable, wrist-free monitoring. Choose this band if you wear wrist accessories, need a stable sensor during weightlifting or manual work, or prefer the upper-arm placement for discretion and comfort during sleep and all-day activity.
