In 2025, wearable technology, including smartwatches, bands, and rings, has become integral for fitness and health monitoring, with companies like Apple, Samsung, and Strava incorporating AI coaching features. At IFA 2025 in Berlin, the Samsung Galaxy Watch 8's Running Coach software was tested, revealing limitations in personalization and fixed training goals that may not align with individual user objectives. The author also explored the Hypershell X Ultra exoskeleton, an AI-powered device designed to assist leg movement during physical activities, which adapts to individual stride patterns using data from over 12 sensors. While the exoskeleton enhances mobility for walking and hiking, it may restrict running performance due to its design. The Hypershell X Ultra includes a fitness mode that allows users to increase resistance, potentially benefiting advanced runners. The contrast between AI software limitations and the dynamic capabilities of AI hardware is noted, with the latter offering promising training enhancements.
