So, I've gotten into swimming again recently, racking up 1km three times a week. Which is about all I can manage, practically, to get to the pool.
I've started trying to train by carrying out some of the same movements just in air. Just the arms, either in front of me, or directly up in the air.
The trouble is, I've found this extremely fatiguing, after 10 or 15 strokes my arms ache and I'm not able to continue.
Has anyone got a clue why this is more difficult without the resistance of water?
