Gym Test (Comfort, Sweat Handling)

Picture this: Mid-set, sweat pouring like a busted faucet. Does the watch slip? Chafe? Nah, not these champs. Garmin Venu 3 feels solid—like a trusty spotter. At 45g, it’s comfy for reps, and that silicone band grips through burpees. Sweat? 5ATM rating laughs it off, no fogging on the AMOLED screen.

Huawei Watch Fit 3? Super light at 26g, like wearing air. Slim profile dodges barbells, and the nylon strap wicks sweat fast. 5ATM holds up in humid gyms, but that voice coach? Blasts like a hype man—heads turn.

Xiaomi Redmi Watch 5 Active clocks in at 42g, boxy but balanced. Rubber strap stays put during deadlifts, and 5ATM shrugs off drips. Screen stays clear, but bezels catch grime.
