For most, impact exercise is a good thing. The more force you apply to your bones, the stronger they become. Unfortunately, the vast majority of the population is physically falling apart due to being sedentary, overweight, and all around just plain horrible to ourselves.
To be fair, many have legitimate joint and bone injuries, or are recovering from surgeries that also require them to stick to low and no impact modes of exercises. There is no shame in that. Low or no impact doesn’t have to mean taking it easy- it just means working out differently. You can get just as intense of a workout while still being mindful of your limitations.
Low Impact Cardio
To determine if something is high impact, ask yourself if your feet leave the floor, and how hard they come back in contact with it. Your bones and joints are required to absorb the shock, and the impact of this can be too much for many.
