Any workout you choose requires some sort of equipment, whether it's the right shoes for a 5K run or the right racket for a game of tennis. And while you don't have to spend a fortune on the latest gadgets and the spiffiest outfits, you do need to make sure the equipment is in reasonable condition, fits properly and is right for your sport.
Experts recommend that runners replace their shoes every 300 to 500 miles (483 to 805 kilometers). Keep the same tattered pair of shoes too long, and you could wind up with a painful problem like plantar fasciitis. The wrong biking saddle or shorts can lead to "saddle sores," and poorly fitting skates can take you out of your hockey game and land you on the bench with a sprained ankle.
Get your gear at a sports store with knowledgeable staff members who can help you pick the right equipment. Your job is to remember to replace it regularly.
