One of the main benefits of exercise videos is the fact that they allow you to work out in the comfort of your own home. Working out at a gym is not for everyone.
Workout videos also give you the opportunity to set your workout time at convenient hours. This can be a particularly important benefit if you have a hectic lifestyle.
Another benefit of workout videos is that they keep you from getting bored with the same workout routine. You can easily change your workout routine as often as you like.
It's hard to commit to something that you don't like doing in the first place. If you like grooving to the beat, then choose a video with dance exercises.
