Right now I am swimming twice a week for 30 minutes, hour and a half practice on Saturday. My Saturday practices are pre-determined by coach so I'm covered there but looking for ideas I can fit in for a half hour on my lunch. Right now I'm doing:
200 WU, free
200 kick, flutter and fly/breast
10x50s on minute fast (trying to keep within 1 or 2 secs of split)
200 cool down
This is great but my goal is to break a 6 minute 500 within this next year and curious if anyone else has some ideas to slip in. Variety keeps me interested!
