I swam competitively 20+ years ago, but had to quit because I developed a serious sensitivity to chlorine (full body rashes are no fun). I've always loved the water, but had to limit my time in most pools to avoid having an allergic reaction. The pool at the gym near my house recently renovated and switched from a chlorine system to a UV and salt water system (yay!), so I'm swimming again.
I'm slowly rebuilding my endurance, and tracking my swims using my Apple watch. (1,200 yards, 35:30 was my most recent swim.)
My question for other swimmers is: Are there any training resources you have used, programs, drills, and such that have helped you be stronger/faster swimmers?
I swim 2-3x a week, and also cycle and do strength training.
