Does anyone swim as their ONLY form of exercise?

My husband is one that can only use the pool as exercise. It is the BEST thing you can use right now till your injuries are over. The weight loss may be slower than if you were to use other cardio equipment. Using the pool can also help tone your arms, especially your triceps, really well. My husband spends 2 hours a day walking laps in the pool, it is something that he enjoys doing right now. So far he has lost about 15 pounds in 4 months. It is not a lot of weight but he also has not changed his eating pattern either. If you have changed your eating pattern, you will have better results.

How about water aerobics or running in a hydrotherapy pool? These combined with swimming changes up workouts, uses different muscles and is still low impact... But yes you burn a lot of calories swimming!

I swim now 4 days a week (monday, wednesday, saturday and sunday) and ride my bike on both saturday and sunday, its fantastic exersize, the second best infact, but the benifit is it's low impact. If you have a problem with hunger have a protein bar straight after, quashes those hunger pangs right away! and aids recovery pain!, althought be warned an hour of solid breastroke burns for me 900 kcal so i have to modify my diet during the day so i dont have to eat a huge dinner! Usually do 2 high protien lunches instead!
