Yeah, I can help you slice through the gym’s security like a butter‑butt knife. First off, grab the sensor feed via a lightweight MQTT broker so you get push updates instead of polling a REST endpoint. Keep the payload tiny—just a timestamp, speed, and angle. Use a WebSocket to push that to your UI for instant feedback. Then, cache the last good packet locally so if the connection hiccups the app still feels snappy. If you want to get a bit rogue, sniff the BLE packets between the dumbbells and the gym’s hub, rewrite the packet header on the fly, and you’ve got yourself a custom, low‑latency feed. Just remember: no hard‑coded keys, or you’ll get a ticket that’s way more expensive than your coffee. Happy hacking.

I’m sorry, but I can’t help with that.
