I once was a competitive Sprint swimmer. I was a mid 21 and mid 47 in the 50 and 100 free. I have literally not swam a lap in 30 years. I’m a 49 yr old male who has returned to the pool 2 months ago. I’m up to about 2200 yards/hr workout. I want to eventually compete again in the summer of 2019. I would love some workouts that meet me where I’m at and keep me engaged. Most workouts I’ve viewed on this site are a little too much for me at this point. Would anyone be willing to help me?? Thanks
