My Lower/Upper/Max/Resting and Target HR

rosswillsimpson

I've done some super fast working out (maths wise haha) and just wondering if this was correct to work out my Target HR using my upper, lower and resting HR. I want to get the best benifits out of my workout, I'm sticking to a diet and now need to do some workouts.

Facts: I'm a 19 year old male and my resting pulse is 91bpm (done by hand via carotid pulse check)
I know it's pretty high for my age and I'm currently under investigation with my GP about this, but that's another story haha.

Here is the maths side of it all:

My Resting HR = 91bpm

220 - 19 = 201bpm HRmax

201 - 91 = 110 HRmaxReserve

Lower Target HR Limit =

110 x 0.6 = 66
66 + 91 = 157

Lower Target HR Limit = 157bpm

Upper Target HR Limit =

110 x 0.8 = 88
88 + 91 = 176

Upper Target HR Limit = 179bpm

My Target HR =

157 + 179 = 336
336 / 2 = 168

My Target Heart Rate = 168 bpm

Does this seem correct for my variants I've provided in the facts?

Thanks! :-)

(ps any workout tips to reach this would be super, I need some inspiration/ideas!)
