30 minutes is not bad!
HIIT is much more intense than normal running! but it takes 60% less times to do but is more effective than stead running!
u do it for 10 minutes at first then build to 20! even 10 minutes owuld yeild the better results than 30 minutes steady running!
P.S. this is no easy work
here it is:
Interval training is the only form of cardio worth doing IMO! except for sex!
High intensity interval training, known as HIIT for short, is the technique of
alternating 30 to 120 second periods of very high intensity aerobics (sprints, also known as the “work interval”) with 30 to 120 second periods of low to moderate intensity (the recovery interval). During the work
interval, you actually push yourself outside of your target heart zone above 85% to the point where you begin to lose your breath. You then
reduce the intensity enough during the recovery interval so you reclaim the oxygen debt just in time to do another work interval.
Example!
Level 3: 5 minutes (warmup)
Level 4: 1 minute (rest interval)
Level 7: 1 minute (work interval)
Level 4: 1 minute (recovery interval)
Level 7: 1 minute (work interval) Level)
Level 4: 1 minute (recovery interval)
Level 7: 1 minute (work interval)
Level 4: 1 minute (recovery interval)
repeat as much as you can!
but you can alter levels to suit youself! personnaly I do 1-2 while resting and go between 8-10 while going fast! it works! just do what suits you best
level being how hard you run! 1 being walking slowly and 10 being as fast as you can!
trust me! if you try this workout! you would wanna come here and shoot me!
it's absolutly EXHAUSTING!
trust me I know!
good luck!
