Thanks Sudie!
Over/Unders
Based loosely on a Chris Carmichael workout that I have used before.
Warm up 5-10 mins.
Main set:
2mins. hill(under LT)
2mins. flat(LT)
3mins hill(under LT)
3 mins flat( LT)
2-3 mins recover
repeat 4times
cool down/stretch
You can start first interval sub/at LT and then try and progress intervals so you finish at LT on hills and just over LT on flats.
Try and keep the transitions smooth from hill to flat as you take off resistance but add cadence to increase intensity.
Have fun!!
