Amazfit unveils Helio Strap Pro with addition motion sensor

The Amazfit Helio Strap ($95 on Amazon) was designed to offer precise sensors at an affordable price, and, most importantly, without any subscription requirements. The new Amazfit Helio Strap Pro builds on that concept, but it’s not just a wristband, it’s an entire workout system. To this end, Amazfit combines the so-called Helio Core Motion HR, which is worn on the wrist or, for more precise data, on the upper arm, with the so-called Helio Core Motion Waist.

The motion sensor, worn around the waist, tracks the movements and stability of the torso during a workout. The collected data can also be combined with data from a compatible smartwatch, such as the Amazfit Balance 3 or Balance Ultra. This allows the system to track not only superficial metrics like heart rate, but also muscle strain, stability, and the quality of the workouts completed.
