Anyone here using swimming as their main exercise to loosing weight? Due to my walking usually 10,000 plus steps daily at work and my right knee getting a bit sore by the time I end work and head to the gym, Swimming I think would be a better option for me as more (straight-line) activities like stair, bicycling, treadmills all add impact to a tender knee and I know it will wind up being an injury that would take weeks to heal.
Whereas swimming should be fine. I am planning on starting out with it tomorrow.
Anyone else here use Swimming?
