Here’s an IM and cords set that I did this morning in a 25-meter pool.
3 X 50 breaststroke on the cord (made it to within a few yards of the end, then used the laneline to pull myself to the wall, turned and swam back assisted)
Four times through, on 1:05 sendoff (10-15 seconds rest):
Repeat the 3 X 50 breaststroke on the cord.
Four times through, on 1:05 (15 seconds rest on the breaststroke):
50 whole-stroke breast with a pull buoy, focus on fast hands
50 freestyle pull, focus on connecting core to catch
50 breast/free with a pull buoy
