"Today's workout: 15 minutes of chasing Fido around the park—he calls it 'fetch cardio,' I call it a new fitness craze!" Sarah tweeted, sharing a video of her dog darting between bushes.

Comments flooded in. Mike joked, "Only if Fido promises not to throw in any squirrel sprints! His training intensity is next level."

Emily chimed in, "I tried this and almost face-planted chasing my own pup. Pet-inspired workouts might be the craziest fitness trend yet!"
