Anyone here use swimming as a main cardio workout? I have titanium in my leg and so running doesnt happen, walking doesnt get a heart beat up, and mountain biking isnt working. I either get really bored and quit or more often i get bored and try to do stupid stuff that almost gets me hurt. So Ive started swimming, plenty of lakes around me! I can drive to one from work in about 10 minutes, we are allowed to use the work truck for an hour of personal use each night so I drive to the lake, change, swim around and then drive home. Ive also noticed that i feel a lot of muscles being worked i wouldnt normally seem to work so Im really liking this new routine! Wish i would have started way earlier in the year though! Question for anyone who does swim, is there better styles to work certain muscles? If that makes sense..... Im not much of a swimmer yet but curious if i should be working on a certain style for a better full body work out?
