I am not an amazing athlete but I do like to stay active. I had previously done the couch to 5K program and I enjoyed that interval training a lot. I have been trying to find something similar to guide me into being a stronger swimmer. I have kickboards and pulls available at the pool so I could incoorporate those. I do much better with a specific plan. I've never swam laps for exercise before so I don't know where to begin.
