If you are looking for a HRM and don't want a chest strap I suggest the Scosche Rhythm 24. It is an optical HRM that I wear on my forearm and it works like a charm. It is really comfortable and reliable. I don't trust my Fenix 5 HR to use it during working out. I tried one time and it was not that great.I haven't followed up but make sure the production issues with the Scosche 24 have been fixed. Lots of issues, mine broke last summer. I still like the Scosche rhythm model, even though I lost it at a race. I'd buy one again, but currently using the wahoo tickr fit for longer battery life. Works great (I know for the OP it's a PITA when the Fenix should already work...)
