Word of mouth quickly spreads through the grapevine at the gym, which can result in our benefit or our loss. Sometimes we can pick up on some great workout tips we’ve never heard before, then on the other hand we can also pickup some bad habits.
Between the advice you get from people you see at the gym, your kids coach, your friends, and your family, it can all be overwhelming. Some of these myths are just harmless myths which may be somewhat based in truth, while others can actually impact your health.
For some reason there is a persistent belief among some gym goers that the treadmill is better on their knees and joints in general as opposed to asphalt. This is the furthest thing from the truth, and can do you harm in the long run.
If you have bad knees or are just looking to reduce the impact on your joints in general, running on the treadmill regularly is not a good option. Doing so occasionally is ok, however you don’t want to run on the treadmill every time you work on your cardio.
The best solution here is to not avoid using the treadmill altogether, but to vary up your exercise. Give yourself a break and allow your body more time to recover by doing exercises that are less impactful on your joints. Try to include swimming, cycling and other low impact cardiovascular exercise in to your routine for a better balance.
While swimming provides us with many health benefits, unless you are swimming for hours on end a day it is not going to do much in the way of weight loss. This may come as a surprise to many people as they see professional swimmers like Michael Phelps consume upwards of 5,000 calories a day, but we have to remember this is someone who trains for much longer than we do.
The fact is that swimming for 30-45 minutes a day isn’t an effective way to lose weight, and it all comes back to the effort exerted and intensity of the exercise.
While moving through water is more difficult than moving through air, we have the added benefit of buoyancy to make up that difference. This makes it easier for the body to support your weight, and thus makes swimming less work than say running or jogging.
