Smartwatches, a helpful tool for bodybuilding?

It's been a bit more than a year since I started strength training 3 times a week. Nothing fancy, just an amateur grinding stats like an Orc preparing for war. During my sessions, I take note of my performances using the old-school pen and paper method, and I love it. I'm not distracted during my workouts and you can't beat its convenience. It'll also make good memories when I leaf through all the booklets I've collected over time.
