What kind of is safe for obese people

Of course you should check with a physician first, but walking is usually safe. Start slowly; a comfortable pace for up to 10 minutes if you can tolerate it. Once you can do 10 minutes easily every day you can increase the time, increasing about 10 percent a week. It is ok to break it up into several mini sessions a day. I would also recommend finding a qualified trainer and adding strength training sessions.
