HIIT  Cardio  -­‐‑   Overview
HIIT  require  strong  bursts  of  intensity  where  your  heart  rate  approaches  75-­‐‑ 8 5%  of  its  
maximum  heart  rate  (MHR)  for  a  brief  period  of  time  (interval).  
After  the  high  intensity  interval  is  completed,  you  reduce  the  intensity  to  allow  your  
heart  rate  to  drop  back  to  50-­‐‑ 6 0%  of  MHR.  
To  calculate  your  max  heart  rate  use  the  following  formula:
MHR  =  220  –  Age
For  example,  if  you  were  30  years  old  your  MHR  would  be  calculated  as  follows:
Max  Heart  Rate  =  220  –  30  =  190  Beats  Per  Minute  (BPM)
 
To  calculate  the  high  intensity  interval  portion  (80%  of  your  MHR)  use  the  following  
formula:
MHR  x  80%
High  intensity  interval  portion  =  190  x  .80  =  152  Beats  Per  Minute
 
To  calculate  the  low  intensity  interval  portion  (60%  of  your  MHR)  use  the  following  
formula:
MHR  x  60%
Low  intensity  interval  portion  =  190  x  .60  =  114  Beats  Per  Minute
 
Therefore  for  the  high  intensity  interval  portion  of  the  cardio  training  you  need  to  
increase  the  intensity.  
This  can  be  done  by  increasing  the  speed,  incline,  etc.  until  you’re  maintaining  a  heart  
rate  around  152  BPM  for  the  allomed  interval  period.  You  should  be  winded  and  have  
a  hard  time  carrying  a  conversation  during  this  interval.  
Once  the  interval  is  completed  you  would  decrease  the  speed,  incline,  etc.  to  allow  
your  heart  rate  to  drop  to  114  BPM.  
Once  the  interval  is  completed  you  go  back  to  the  high  intensity  interval  and  repeat  
for  a  specified  amount  of  intervals.
