Running vs. Walking? I get this question a lot, here is my opinion, supported by 15 years in the fitness industry, certifications & 2 degrees.
Running is great for fat burning intervals, but steady running over a period of time can wreck havoc on most bodies. There is a reason you don’t see too many 75 year old joggers, but you will see 75 year old walkers, swimmers, and even bikers.
Name a runner who doesn’t have some type of back, knee, foot, or hip issue as the miles and years add up.
Also, running over an extended period of time, becomes catabolic, meaning it eats muscle.
Muscle is hard won. The last thing you want to do is lose muscle as you log miles running on the treadmill or on the road.
Walking is low impact and done correctly can rev up your metabolism and burn up body fat.
A great way to get your metabolism going is to take a fast walk right after you wake up. Keep it basic (staying 70% of your MHR). Just get up and go.
If you’re going to use a treadmill, you can take advantage of doing intervals. Increase inclines and speed for bursts of a few minutes, then ease off. Then increase incline and speed again. You can mix it up.
Last but not least, if you’re using a treadmill, DO NOT hold onto the hand grips. Holding on reduces your fat burning by 20%. Make every min count!
