Combining swimming and strength training

I plan to strength train. Since the gym with a pool is a bit of a drive, I'd also like to combine the session with strength training. Lately, I've been thinking of the order of workouts: swim then lift, or vice versa? Since it is good to stretch before strength training, I decided I would swim first and then strength train. This way, the swim would loosen and warm up my muscles, and if I were tired, I'd just use less weight.

This opinion is also the general consensus on a thread at TriNewbies. There are many reasons, some of the best are:

• Never swim with poor form; overdoing the strength training before the swim might result in poor swim form
  
• Save your best workouts for swim/bike/run workouts; strength training is secondary
