CELEB TRAINER TIP

US fitness pro Dalton Wong, who keeps Jennifer Lawrence (right) and Kit Harington in shape, says stop using food as a regular reward. “Most gyms have shakes, juices and healthy nutrient-rich foods, but don’t head for them just because you’ve worked out. That date brownie might be healthier than a regular brownie, but it’s still calories that need to be burned off. If it’s an occasional treat or you’re genuinely hungry, great, but don’t make it a regular reward.”
