If you’re walking to keep joints from getting stiff, know when to eat and drink to maximize benefits. Walking too soon after eating makes it harder, strains your heart and makes burning fat near impossible. So wait 30 to 40 minutes before exercising to allow digestion a head start. Also, drink 8 gulps of water before you start walking, sip water during your walk, and drink 8 gulps after. Exercise and hydration are the key to success!
