Thanks all for the advice new to turbo training
I cycle 2 miles to work then jump on the trainer every day/morning before work. Is that all I should me doing 2 x 20 or 3 x 10. Is their any other workouts that I could do. Have about 50 minute be for I have to go for a shower.
You could squeeze in a 5x5 once a week. 3 minute rests. Don't neglect warm ups. Once you're comfortable with the intensity (4-6 weeks I would say) you could add specific workouts like the
Hour of Power. It will take you a while to learn to pace your intervals appropriately. They should be evenly paced across their duration ideally, and you should feel all done in at the end of each interval. Make your rests 5 minutes, between intervals. That doesn't mean get off the bike, just relatively easy pedalling for 5 minutes.
But a lot depends on your goals, strengths and weaknesses. Prescribing whole training programs over the internet without knowing your specifics is likely to be sub-optimal. My suggestion would be to get a good training book, and once you understand the principles, build your own training program to fit your goals, that way you can build periodization around your life schedule, and target your weaknesses.
But you won't go far wrong with a couple of months of a steady 2x20 diet.
