I am 35 so mine "should" be 185.
A few weeks ago I watched a Horizon documentary about HIIT
so gave it a go, cycling up a really steep hill (20% in parts) near my house... its the "quasi-countryside". HEART RATES:
First time - 183 (about a week ago)
Second time - 185 (the very next day, when I didn't realize you shouldn't do HIIT every day lol)
Today - 189 (long break - about 5 days later)
I made my HR monitor beep at me today hehe. 101% of max oops.
So as I do the HIIT more, it seems to add 2 or 3 to my max each time.
Yeah there will be a plateau where the MHR cannot go any higher for me personally, but when?
Someone that is 35 could I guess get past 190 but isn't this really high even for the most elite athletes? For example I never heard of anyone over 200 (regardless of age) but then I have not spent any time studying this much.
If I have got it from 183 > 185 > 189 in three training sessions is that a good sign?
But if that is already +5 on the normal estimation, isn't that quite dangerous?
If you really want
to get fitter, I think danger kinda has to be your middle name, to a certain degree.
I mean some people will do HIIT type of training and say "thats enough" whereas others will keep going until they are literally nearly feeling sick and wobbling on the bike.
Compared to "long" rides (over 25 miles or, over 2 hours) this HIIT is making me feel a lot better than those long rides ever did. Fatigue isn't as high and yet I feel as though I have "done" more, used more energy in less time, this way it feels like I am actually getting somewhere, forcing myself to get fitter as opposed to aimlessly averaging 12.5MPH for hours on end, like it says in the Horizon programme that might work for some but for others you need to do drastic stuff, but then those types might also benefit even more from that than the people riding 2+ hours at a time are benefiting.
Programme said it takes 6 weeks (3x a week) with HIIT as opposed to 2 weeks if you do longer "easier" rides. The thing is after the 6 weeks, you're on a level playing field and the progress between HIIT and normal cardio is about equal, its just that HIIT takes 4 more weeks to get into that mode, I guess because at the end of the day you're riding only 4 or 5 miles and taking 18 minutes to do it (15 miles a week tops) as opposed to 25 miles and taking 2 hours (75 miles a week).
Exercise is bizarre and really complicated if you let it be.
