With some recent knee problems (osteoarthritis) I have been advised to add swimming to my exercise routine to replace the elliptical machine and treadmill. I finally got in the pool today and swam some laps. There were no issues with my knee while swimming - Yaaah!

It's been a while since I swam for exercise and I need some advice on how to add swimming to my routine. For example:

- Can I swim after lifting weights?

- Should I swim before lifting weights?

- Should I swim only on days when I am not lifting weights?

- On days when I swim should that be the only exercise of the day (i.e. not added to other cardio like rowing)?

- In the pool I noticed people holding onto styrofoam floats just kicking and not using their arms. What's going on with this?

- In the pool I also saw an older gentleman walking for about half a lap and then swim for the rest of the lap. This may be my speed these days. Has anyone ever tried this and what are the advantages of this technique?

Sorry for all the questions, but I really am clueless about swimming.

@@Inner Surfer Girl YAY!!!

I have a pair of very large foam dumbbells i bought online, they are made by Theraband and have lasted me for five years of vigorous 3x a week use. When I was starting out on swimming (the first regular exercise that ever stuck with me!), they were invaluable, and much more sturdy than the cheap ones at the pool. I now have a comprehensive workout but starting out doing a series of flexibility exercises in the Water made me get started.

Swimming seems to be a good replacement for the treadmill and elliptical machines that I need to stay away from. Today I used a kick board with swim fins for some variety. Hopefully I can make swimming a regular habit.
