Always check with your doctor before starting any new exercise program, especially if you have health conditions such as heart disease, high blood pressure, or arthritis. Your doctor can advise if a spin class is safe for you and can give you tips on how to modify the workout to fit your needs.
Here are some other suggestions to help you choose the right spin class for you:
Read online reviews on Lessons or Google
Watch an instructor in action to see how they interact with the class.
Take a trial class to see if you like the class pace and instructor's teaching style.
Ask about package deals or monthly memberships.
