Interval intensity
Expert advice needed:
I've been doing a 20 minute session: 2 sets of 5 x 30second sprints with 30 second recovery...and seen great gains. But I'm wondering about which approach to intensity is better, in 2 areas:
1. For each effort, should I try to start less intense so I can maintain consistent effort over 30 seconds, or start all-out and let myself fade?
2. For the whole session, should I start the first efforts all-out, knowing that the power output will fade as I go, or start at a lower intensity so I can maintain consistent power for each effort? I suppose that would mean that only the last effort would be all-out.
Thanks!
