First I was like : YES swimming!!! (I'm a swimming teacher as a student job)
but all I see is : crawl chest...
I'm not happy for you!!
if you want a REAL manly swimmer body : butterfly all day long!!
good genral conditionning 40-60 min swim training is my personnal funzy pyramid :
200m crawl warm-up
100m breaststroke
50m backstroke
25m butterfly stroke
rest by doing 100m kick crawl
then
25 m butterfly stroke
50m back stroke
100m breastroke
200m crawl (sprint)
100m crawl only arm
50m back only arm (for those shoulder)
50m arm breaststroke (feel the pain!)
and you finish with
3x 100m QNI (25 butterfly 25 back 25 breat 25 crawl)
and a sprint 50m butterfly
you add a 100m free for sprint against other et voilà à good 1500m that you'll have fun doing!
