Paddling muscles...

Yo.
So I have awful paddling fitness, like that of a 12 year old asthmatic girl, and need this to change.
I am 73kgs and pretty fit. I run, cycle and play football a low. I also do pull ups, sit ups and press ups at home. I can swim 80 lengths of breast stroke in an hour but cannot do more than 2 lengths of front crawl without drowning.
I have started swimming at my local pool with a float tucked under my rash vest and one between my legs and doing lengths of just arms. This feels like it will help but the biggest area of weakness is around my elbows? My shoulders need more strength but its around my elbows and forearms that get the most grief.
Can anyone recommend some out of pool excersises I can do to increase strength other than what I am doing? I am using a thick rubber band (cannot remember the name) I got from the physio to try to increase my shoulder strength and flexibility.
Cheers
Dan
