Hi runners,

I have a question on HIIT and i hope that this a right thread to ask for help.

I did my HIIT last night and i felt that i can hardly cope up with the hearth rate thou, i m trying the beginner's HIIT which is 30sec sprint (173bps) and 90sec brisk (125bps).

-1min warm up
-sprint 30sec - heart beat only reach 150 - 160bps
-brisk 1 min - 140+bps
-try to sprint for 30 sec - it only reach 150 -160bps again and tats the end of 30, the time to hit 175 needs to be more than 30sec ...

So i was wonder how can i hit 173+bhp ? during the intensive 30sec, the time seems to be so insufficient for me to hit 173+bps, and my brisk owas hit ard 145bhp. So how do u calculate ur heart ?

should that be in that 30 sec :--

first 10 - increase hearth beat
following 10 sec - catch up with the beats and reach the max beat
last 10 - cont with the max beat

is tat sounds alright? and i read from some other forum they claim that, shorten the rest time may be easier for me to cope with the hearth beat...

Try a 1:2 ratio, Jamis.
For example : 20 seconds sprint, 40 seconds jog;
What I do is 2:3 ratio but with a shorter sprint interval.....i.e I do 15 secs sprint (70% full effort) and 25 secs jog (5:00 min/km). I find that this interval training improved my performance substantially...probably u can try this out.

I plan to do skipping next time, as there is no much place for me to sprint and i dont like the thredmill and the cycling machine.

Yeah i think i should do 1:2 and try it out. By the way, do u measure ur hearth rate?

AFAIK, the only measurement for heart rate is BPM (beats per minute). If Ur heart beats at 173 beats per second (bps), it would've burst out of Ur chest already by now.

Did U use any instruments to measure Ur heart rate, i.e. heart rate monitor/wristwatch with heart rate sensor ?

I'm not familiar with HIIT concept of training, although I do regular intervals & fartlek in my training. If U can't reach certain heart rate during the run, causes might be :

1. Ur not running hard enuff;
2. U haven't warmed up enuff;
3. Ur too tired U can't reach certain heart rate.

Take my interval sessions for example:
I run 5 x 800m at 5:35/km pace, that would take me around 4:00 - 4:10 to complete each rep. My heart rate would top around 165-170bpm thruout the 4 mins. Between each rep I recover to about 110-120bpm in about 2mins or half the interval period. My max is 187bpm (age formula). Last Tuesday while doing fartlek, I hit 214 bpm... How ? I dunno ..  hmm.gif

So U see, for me, it takes 800m/4mins (avg) to get me to 170bpm. Maybe in 30 secs, U need to really, really sprint to get up to 170bpm. Or maybe do hillsprints. I've hit 170bpm for hillsprints in less than a minute, no prob.

& U mentioned there Ur warm-up is only 1 min. U sure thts enuff ? Maybe U need to warm-up at least 10 mins by slow jogging to get warmed up. & I use Polar RS300sd for all my workouts.

Sorry sorry its bpm lol, by the way i dont have any hearth rate monitor i just take the reading from the cycling machine that i tried out.

Wow tats insane, 170bpm for 4 mins.

I m just wondering if that 30sec gona be my 170bpm or time for me to hit 170bpm?

I didn't bother to check my heart rate like u stated there b/c I don't have any equipments.....I just check them with the distance and route that I use.
If I use the 2:3 ratio, I can only last about 3-4 km. (higher bpm)
If I use the 1:2 ratio, I'll last about 5 km. (lower bpm)

icic, guess i better try out the 1:2 ratio first. It has been ages i never do my cardio. sweat.gif
