below is an interesting computer model of the skeleton doing the 4 IM strokes. It shows what muscles are working at every stage. Pretty cool.

This week finished in a great way as we did really hard series of sprints- all out after a warm up of 1000meters. We started with all out 25s then 50s then 100 the last 50 was butterfly. Great and body breaking workout. Nice to have the weekend to recover.

I wonder if it is worth going to 3 days a week for the recovery process.? any thoughts?
