Advice on training programme
Hello all, this is my first post here so I hope this is appropriate. Last year, I bought the H10 heart rate chest strap monitor to track my training because I really want to increase my endurance. For reference, my primary sports are running, Muay Thai, and bouldering.
Anyway, I tried getting into zone 2 running using Polar, but quite honestly it’s been a pain because of how quickly my heart jumps to Z3 and how long each run takes as a result. I’ve seen, of course, that many people have said that the heart rate zones on the app are calculated in a rudimentary fashion, but I was wondering what everyone else has used that they found to work well? Also what volume of Z2 work did you have to do before you noticed gains in your overall energy use? Does working out under Z2 (long walks) help with this as well? If anyone has any advice on a training programme that worked well for them I would appreciate it very much.
I’ve attached three of my workouts (1x Muay Thai, recorded as kickboxing, 1x bouldering, 1x z2 run) in case it helps. For further reference I’m 158cm/5’2” and weigh 50kg/110lbs with a resting heart rate of around 55bpm.
