1st year masters 30-34 I swam 3500 yds 4 days a week maybe 1-2 days of weights my in season best 100 time was 54.17 then taper to a 53.30
2nd year masters 30-34 i swam 3000 yds 4 days a week with heavy emphasis on paddle/fin and heavvy sprinting. Did weights 3 days a week and added a spin class to mix things up and improve my legs a little. My in season 100free suffered, going a 55.5 but I had a huge taper and went 52.1
3rd year I'm a maniac!!! 3500 3-4 days a week, heavy weights 4 days a week, and I hit the spin class at least twice a week cuz i tend to hate swimming more than 5 days a week. And yoga twice a week. So far my 100 time is 54.0 but my splits are a lot mmore even than ever and my 50 time is way faster than in the past 2 years. Plus I tend to hold sets better during practice.
I find it better to give myself variety so as not to get burned out or bored simply by swimming 20,000 yards a week
