bahamas, I see my whole problem in your words! I also have spin classes booked throughout next week and will be off for a ride with my boyfriend soon (I might meet him at the top of the hill 10 minutes after he got there, if lucky!) and then we're off to Richmond Park (please, pray for my soul
) and I am also well aware this is far from enough so I got a four week exercise plan off my personal trainer yesterday that I aim to work on, at least, 3 times a week (4-5 would be ideal) that is solely a mix of cardio and resistance - one day each. she will be revising my progress in 2 weeks, and then at the end of the 4 to keep it going to elaborate a new one.
I am definitely not a fitness freak but I confess it seems doable. and I am also doing it mainly to get better fitness levels so I can ride my bike at the same ease I would a few years ago.
If you want I can be nice enough to write it down and send it to you, if that helps
