If I have an indoor aerobic session planned and no access to Netflix, I do the following
5 mins / 4 mins /3/2/1 on AD, Rower, skipping.
Move from one piece of kit to another without breaks, the above results in 45 mins of aerobic work with zero boredom.
If you only have 2 pieces of kit, ie. AD and skipping rope, then the above timings gives you 30 mins of work..... however I find it hard to keep the HR low enough when skipping, so this necessitates some slowwwwing down on the rope turns to ensure I'm working at the right level.
Just a couple of thoughts
