Speediance Strap will be officially launched on 17 September 2026. This screenless wearable adds a metric to the Speediance ecosystem that has previously been difficult to measure in a way suitable for everyday use during training: core body temperature.
Rather than aiming for a uniform, all-encompassing solution, the Strap focuses on specific training scenarios and examines in depth the relationship between body temperature and training performance. The emphasis is on thermal adaptation, heat stress and the optimal training window.
The Speediance Strap will also be on display at IFA 2026 in Hall 12, Stand 121.
Whilst training equipment primarily tracks performance during a session, core body temperature provides additional insights into how the body responds to exercise. Continuous measurement at the wrist is made possible by Calera® technology from the Swiss sensor company greenteg. Speediance thus incorporates a physiological signal into a wearable device that can be integrated into everyday training routines without the need for a screen.
The Right Moment for Performance
Core body temperature fluctuates throughout the day and can provide insight into when the body is particularly ready for physical exertion. The Speediance Strap uses these individual temperature patterns, amongst other things, to determine a personal ‘peak window’ for strength and performance-oriented training sessions.
Even during training, changes in body temperature can provide additional guidance: for example, it allows you to tell whether the body is on the verge of overexertion, enabling you to take early action to prevent this.
More Context for Recovery
The Strap’s added value becomes particularly apparent when viewed over longer periods. The individual temperature trends can help to better contextualise information on sleep, recovery and stress. Rather than focusing on a single measurement, this creates a personalised trend that can be viewed alongside other training and recovery data.
The Speediance Strap is expressly not designed as a diagnostic device. Rather, it complements the training data already recorded by the Gym Monster range by providing a further perspective on physical condition – thereby creating a link between what happens during training and the conditions under which the body begins the session.
The Speediance Strap can be used without any additional subscription. Various membership options are also available as an optional extra to unlock further features.
