Most fitness trackers focus on cardio—but what if your workout is all about lifting heavy, building muscle, and crushing sets in the gym?
In 2025, strength training wearables are finally catching up. Today’s best trackers offer rep counting, rest timers, muscle load insights, and even form feedback. Whether you’re doing CrossFit, bodybuilding, or simple home strength circuits, the right fitness tracker can help optimize performance and recovery.

Tips for Choosing a Lifting Tracker
1. Do You Want Rep Tracking?
If you’re doing sets and supersets, go with Garmin Venu 3, Apple Watch + Strong, or Axe Wearable for accurate tracking.
2. Focus on Recovery
Strength gains come from rest and readiness. Whoop 4.0 is ideal if you’re training every day and want to avoid burnout.
3. Smartwatch vs Sensor
If you want full lifestyle tracking (messages, payments, music), go Apple or Garmin. If you’re after pure data and form correction, Whoop or Axe might be better.
And the best is…
Most wearables do cardio well—but strength training needs a different kind of feedback. For lifters, the Garmin Venu 3 is the best all-in-one solution. Want smarter recovery? Go Whoop. Prefer gym-focused apps and timers? Apple Watch Ultra 2 crushes it.
