AirDyne Intervals 4/15/11
Great Airdyne workout today. Used the big fan bikes at BU. These are clearly the hardest of the three versions of Airdyne.
4×1 mi with my good friend Ken
2:41 work 1:00 Rest back to 110 BPM ( hearrate at the end of interval 1 was about 160)
2:41 work, 2 min rest
2:42 work, 2:20 rest
Give this one a try. For the new small fan Airdyne think around 2:30 per mile.
