Confused about different types of training sessions
I'm trying to create a training plan from scratch but just when I think I've cracked it I come across more confusing jargon!
I'm reading Sir Chris Hoy's 'How to Ride a Bike' and he has a few example training plans and example sessions, but all of the sessions have different names. Some are easy to understand like threshold sessions, strength and conditioning sessions and endurance sessions and I'm fine with those. However, there are also 'micro-interval sessions' (which are on a reduced week so I think that just means a reduced-load or easy interval session), 'speed and power sessions' and 'capacity sessions'.
What are the differences between these types of sessions, please?
