Treadmill inclines are very useful to get fitter and healthy by running the same speed for the same time. The incline makes your run harder so you burn more calories which is good for weight loss if that's what you're aiming for. Inclines give some variation to your treadmill workout and can replicate running outside in energy cost.

Inclines are ok for walking

If you're walking on a treadmill then inclines are recommended, in fact, you can use an incline to your hearts content. You can make it as steep as you like and you'll make your walk much harder. You often see walkers on a treadmill in a gym with their arms swinging as they struggle to walk on a steep incline.

You can set the incline up to 15% which is around what most home and commercial treadmills go up to. This will work those leg muscles a lot as you push your feet forward to get up the hill. We have routines that help you walk up hill on a treadmill like these 3 treadmill hill walking plans. This uses the incline up to 6% to help you lose weight by walking.

Avoid steep inclines when running

Running on a treadmill is a bit different. When you're running you lift your feet off the ground in every stride. This creates a big impact through the joints every time your foot lands. For this reason we don't discount trying inclines altogether, as they appear in nature so we can deal with them to some extent.

However, running non a steep incline for a long period is not good for you. Because of the increased impact, running on an incline shouldn't be done for more than a few minutes. This is to protect your legs, there's no reason to run up hill for long periods, you may want to burn more calories but you're better off running for a longer period to burn the same amount.

When running on an incline is ok

Inclines when running on a treadmill aren't all bad. There is a case if you're training for a race or when you want to replicate running outside. In this case it's a good idea to set an incline to run at. This incline is very small and is there to make the energy cost of your run the same as running outside.

The science says replicating running outside is possible and you can do it by setting the incline to 1%. This means the energy cost is the same for the distance you're running to. Setting other inclines more steeper is ok as long as you're not doing them for long periods. You're unlikely to meet a 3 minute 6% hill on your run outside so don't do it on the treadmill.

Summary

It can be very tempting when running on a treadmill to turn that incline up, just to make it harder and get more of those calories burned, more of the fitness levels and health benefits. Treadmills can be boring for some but they still need a level of respect when exercising on them. They feel easier but can still cause over use injuries especially when the incline is used.

If you're deciding what incline you should run on a treadmill and you're relatively new to exercising, then you should just think about getting your technique and running form correct. You need to concentrate on getting to the CDC recommendation for fitness in adults and try to run at least 1 hour and 15 minutes per week. This is far more important than setting an incline.
