From step counters to sport-specific coaches
Sports smartwatches are wearable devices that combine heart rate tracking, motion sensors, and sport-specific software to give athletes real-time training data, post-workout analysis, and coaching insights tailored to their chosen activity. The latest wave of devices goes beyond general fitness tracking to address hybrid training, obstacle-style races, and niche sports such as surfing and trail running. Brands are building sports smartwatch sensors into modular systems, pairing chest-, arm-, or waist-mounted trackers with a hybrid training watch to map how the whole body moves and tires during a session. For serious athletes, the focus is shifting from “how many calories?” to questions like “how stable is my core under fatigue?” and “what is my true training capacity this week?”. Three new products stand out: Amazfit’s Helio Strap Pro system, Casio’s surf-focused G-Lide GBX-H5600, and the Amazfit Cheetah 2 Ultra trail running smartwatch.
Amazfit Helio Strap Pro: Dual sensors for HYROX and hybrid training
Amazfit’s Helio Strap Pro positions itself as a dedicated HYROX training device, built around dual sports smartwatch sensors that split duties across the body. A Helio Core Motion HR sensor wraps around the upper arm or wrist for heart rate tracking during HIIT, strength, and functional workouts, while a 9-axis Helio Core Motion Waist sensor monitors torso position, movement quality, core stability, and muscle load. Paired with the Amazfit Balance 3 or Balance Ultra hybrid training watch, it unlocks HYROX Race and HYROX Simulation modes that log classic events like sandbag lunges, SkiErg, wall balls, rowing, sled push and pull, farmer’s carries, and burpee broad jumps. The Zepp App pulls all streams into a structured summary and adds sleep, recovery, and habit tracking. Amazfit calls this a Hybrid Training System, using its HybridCharge Energy Intelligence metrics—BioCharge, Training Load, and LifeLoad—to show how strength, endurance, and daily stress shape performance session by session.
Casio G-Lide GBX-H5600: Surf-first features and solar-assisted endurance
Casio’s G-Lide GBX-H5600 brings a classic square G-Shock shape into the heart rate tracking smartwatch era, aimed squarely at surfers and outdoor athletes. The watch combines an optical heart rate sensor and blood oxygen estimates with a three-axis accelerometer to track steps, distance, pace, and multi-sport sessions. It adds surf-focused tools such as tide graphs, moon phase, and sunrise/sunset data, with a smartphone app supplying tide patterns for about 3,300 surf spots worldwide. Casio uses a high-resolution Memory-in-Pixel display for bright-sun readability and a lighter 47-gram case made from carbon fiber-reinforced resin. Power comes from USB plus solar-assisted charging; with continuous heart rate tracking during activities, Casio says the battery can last up to 35 hours, while watch-only mode stretches to about a month. Priced at USD 330 (approx. RM1,550), the GBX-H5600 gives surfers a sport-specific hybrid training watch without losing the familiar G-Shock feel.
Amazfit Cheetah 2 Ultra: Trail-focused performance on a budget
For off-road runners, the Amazfit Cheetah 2 Ultra offers a trail running smartwatch that tries to undercut premium competitors while keeping key performance features. In trail-running mode, Amazfit claims up to 33 hours of battery life, with reviewers measuring about a 13 percent drop over three hours, which “would actually equate to roughly 25 hours.” Athletes can extend life dramatically by reducing GPS sampling, turning off multi-band GPS, dimming the screen, and disabling always-on display, pushing runtime to a quoted 228 hours for longer adventures. The watch highlights climbs with color-coded elevation segments, similar to Garmin’s ClimbPro, helping runners mentally prepare for ascents and descents. While Zepp OS lacks major streaming apps, LTE, or advanced satellite options, performance for running, swimming, and gym work has been praised as reliable. For trail runners who value mapping, navigation, and long battery over ecosystem polish, the Cheetah 2 Ultra is an appealing lower-cost option.
Why dual sensors and hybrid modes matter for serious athletes
What unites these devices is a multi-sensor approach that turns a heart rate tracking smartwatch into a more complete performance lab. The Helio Strap Pro’s split arm and waist sensors show how upper-body effort, core stability, and movement efficiency change across a HYROX workout, while the paired watch tracks pace, volume, and recovery markers. Casio’s G-Lide couples heart rate and motion data with surf-specific environmental metrics—tides, moon phase, and sun times—to help athletes plan sessions around conditions, not just heart rate zones. Trail runners gain color-coded elevation cues and long GPS endurance from the Cheetah 2 Ultra, giving clearer insight into how climbs and descents affect fatigue. For hybrid athletes who mix strength, endurance, and skill-based sports, these sport-specific tools mean more than step counts: they turn everyday sessions into structured experiments on how the whole body responds to training load over time.
