150BPM for pre workout warm up cardio is WAY overkill. Your just trying to get the CNS stimulated and blood flowing everywhere.

180 on regular cardio? How old are you bro? That sounds extremely high. I know for myself I'm 36 and my target BPM for High intensity cardio ie: walking at a 15 degree incline at 3mph is 145-ish. Even doing interval sprinting I never get above 165 bpm.

I mistyped here. i meant to say 170, but I honestly don't think that the machines work correctly.

but this could be ellivated due to preworkout/diet pills.
my blood pressure and normal bpm are all in the correct range, so im assuming its the stimulants or machine failure. When i do get that 170ish number tho, almost immediately it drops down while resting 10-20 bpm's. but yes that is sprinting, and after about 15-20 seconds of rest im back to 150/160 range
