I am getting back into swimming. I currently try to swim laps every day. I do approx. 1000 yds. My endurance is not good. I can only do 75 yds. non-stop only about 3 times. It takes me about 45 minutes to complete the 1000 yds. I do 200 free, 100 back, 100 free with pull, & 100 free each set. I quit swimming 40 yrs ago. Too many years of smoking and not taking care of myself. Can someone give me tips on a daily workout to improve endurance, stamina, and speed? My goal is to compete in Senior Games in the 50 and 100 free. Thanks
