That's odd, I think they are great for exercise. Swimming is an aerobic exercise with light resistance. I mean is this a low impact exercises vs. high impact issue? Yes, you burn more with high impact but if you don't like it but like low impact, do it.
Walking is my main daily activity. I wish to implement swimming in the next couple of months :) I do low impact cardio daily with heavy lifting 3 times a week (also eating at a deficit), getting decent results even though I am only one month in with lifting. If I get my goals met and look great, all those who say high impact is the only way, can go take a long walk off a short pier.
I don't plan on running/jogging for weight loss, though I have been advised to try it (from cc'ers), I may try it for fitness/endurance after but not for weight loss/maintenance.
Swimming and walking not exercise? Who is smoking what??
Both are excellent forms of exercise. I have an old knee injury that torched the cartilage in my right knee, and that makes it nearly impossible to run, so I power walk instead. With the hills in my town (San Diego), it's easy for me to hit my target heart rate and keep it there. Same goes for swimming. I don't do it often, but when I do it's battling against surf, so it is an amazing full-body workout.
Try adding strength training too. A combination of low-impact cardio and weight lifting has been my go-to from the beginning. If walking and swimming weren't beneficial, I guess that my now normal lipids, blood pressure and resting heart rate (58 down from 85) must have happened by magic :)
Some people literally believe the earth is flat.
You should not listen to those people.
Yes swimming is great exercise walking is very good exercise
cnichols - there are people who believe much more stupider things than that, unfortunately.
