Question

how can fitness walking be beneficial?
o it uses all the major muscle groups.
o it isolates and strengthens the leg muscles.
o it uses all the major body systems.
o it isolates and strengthens the core muscles.

Explanation:

Fitness walking is a full - body activity that engages multiple muscle groups. While it does strengthen leg muscles, it doesn't isolate them. It doesn't use all major body systems like the digestive system in a direct active way during the walk. And it doesn't just isolate and strengthen core muscles. It does use many major muscle groups such as leg, hip, and arm muscles.

Answer:

It uses all the major muscle groups.
