An incline treadmill can offer a number of benefits, both physically and mentally. First, walking or running at an incline can help you burn more calories than if you were doing the same activity on a flat surface. This is because you're working against gravity, which requires more energy. In addition, using an incline can help to tone your legs and butt muscles.
If you're looking for a mental boost, then using an incline treadmill can also help. The act of pushing yourself to walk or run at a higher incline can give you a sense of accomplishment and help to increase your endorphin levels. This can leave you feeling happy and motivated to keep up with your workout routine.
