Freestyle IM - (FrIM)

FrIM stands for Freestyle IM. In FrIM, you do the regular IM order, but replace butterfly with freestyle. It's meant to be a less tiring alternate to regular IM, so you can train for longer, or focus on the backstroke/breaststroke parts of the IM. It looks like this:

1. Freestyle
2. Backstroke
3. Breaststroke
4. Freestyle

So a 100 FrIM would be:

1. 25m Freestyle
2. 25m Backstroke
3. 25m Breaststroke
4. 25m Freestyle
