Do you have a personal coach or do you control youe workouts yourself?
I lose patience when somebody tells me what to do, so for me Beets BLU hrm was the best option, what about you, guys?

I don't do anything, keeping fit and healthy is just too hard, man... I just take the bike some time when there's not enough money to fill up the bike... Yeah I know it's unhealthy but why spend all your time being healthy when you die anyways!
