feel slow, notice that my biking needs work. I am using a trainer, so not sure how real it is bike seems that I have an average 17 MPH and need to be in the 20 mph if I want to do well.
Warm up with 15 minutes of easy cycling.
Ride 10 miles at a speed that will total at 45 minutes. Stay in Zone 1- Zone 3 for majority of the ride.
At any point during your ride, perform the following twice: focus on raising your heart rate zone so that it's between Zone 3-Zone 4. While in Zone 3- Zone 4, continuously ride for 6 minutes. After the 6 minutes are up, return back to riding in Zone 1-Zone3
Noticing that my biking needs some more work,
