I swam competitively in High School and College. The distance I used to swim turned me off from swimming for many yrs. 10-15k a day.
After 15 yrs ive decided to try it again. My best masters experience were workouts that averaged 2500. I felt 40 min of hard swimming was manageable with my other daily duties and did not scare me away.
A good warm up. 600 yards.
A kick or stroke set. 600 yards.
Then a core set -1000 yards. 10x 100, 5 x 200 im etc.
Warm down.
Can this cut it 3-5 days a week to get in primo shape?
The majority seem to be saying 3500.I almost never swim more than 2500/dayX4-5 days/week and am pleased with my results.I also lift weights 2X/week(generally on swim days so that is still 4-5 workouts per week.)If I was doing your workout,for me the key would be the intensity of the core set.I am training for the 3 BRs mostly so my core 1000 would be as 25s,50s or 100s at race pace(25s as sprints,50s at 100 pace,100s at 200 pace.No I wouldn't do 20X25 sprints,but I might do 8X25 then a recovery swim then another 8X25.)To do race pace I am giving myself enough rest,like 50s on 2 min or sometimes even longer.If I can't make my goal time I give myself more rest or throw in a recovery swim.If I swim 5X/wk I have made one of the swims not race paced,but rather all recovery swim speed or drills to let my body recover.
