Answer:
It is important to ease into an exercise program because whether the program is fairly new to you, or you've been doing it for years, your limits may change. And you don't want to risk injury during the exercise- this can include cramps, charlie horses, and so on. That's why it is also important to have a spotter or someone there to help when you have reached your limit or to notice when something is going to risk your safety. I hope this helped!
