Wanting to swim (also doing weight training)

This is new to you.... Your lungs will tell you how much to rest when you are first starting out. I would say you should be a little winded when you reach the wall. Then allow yourself to catch your breath and go again. At first, you should probably reference the clock only to tell you how much time you needed to recover for each distance, rather than letting the clock dictate when to go again. Then you use those times to improve upon. Just using the short set that I posted as example... let's just say... If you need 45 seconds between distances today, The idea is to set a goal to only need 40 or 35 seconds to recover for the same set "2 weeks from now" and so on. Once you acheive that, then you can increase your distances using the same model. keep in mind, there are numerous ways to approach your training. I'm just trying to assist you in getting you started.
