On the thr calculator it says I need to be between 115 and 134 why so high ?I don't know any bbr who does cardio at this level.I have been doing cardio between 115 and 120 and the fats loss has slowed and my diet is on point.I calculated my mr rate at 65% of the suggested hr on the treadmill using the age scale and I came up with 98.8 so what gives?
