Not proud to admit but I average 8 cups of coffee a day, my tolerance is through the roof. I also pound coffee in the morning because I'm so groggy from my night time meds. Can't be good for you! So I'm cutting back to six, then hopefully 4, then 2 strong cups. Weening seems like a good option.
Plus the price of coffee is outrageous, even the cheapo Folgers is $10 for the large.
How much is rhr influenced by caffeine vs exercise? Because I'm trying to my rhr as low as possible but don't want to cut back on my caffeine intake.
Endurance athletes love caffeine and their heart rates are still in "Either this man's dead or my watch has stopped" territory so exercise must be a bigger factor. No idea if there's a tipping point, where you need to run ultramarathons to cancel out your Balzac-level caffeine intake.
