You spruce up your house when the seasons change, so why not do the same with your workout? From gear to attitude, heres what to toss—and the best way to to replace it.

Katy DockrillDitch: Old walking or running shoes
Instead: Invest in a new pair of kicks, because worn-out soles are a quick path to injury. Write the purchase date on the tongue or side of your shoes and let your weekly mileage be your guide. If you walk or run 10 miles per week, replace your shoes every 12 months; 15 miles, every 8 months; 20 miles, every 6 months; 30 miles, every 4 months.

Instead: Drink 4 to 6 ounces of water for every 15 minutes of exercise. Sweating away even a tiny portion of your body weight can doom your workout by making your heart beat faster and causing you to feel weak and tired.


Ditch: The idea that more is better

Instead: Focus on the quality, not length, of your workout, Davis says. Instead of walking or biking at one speed for an hour, halve your workout (and burn the same amount of calories) by doing sprint intervals—30 seconds to 2 minutes at a very fast pace, followed by 2 minutes at normal pace.
