In honor of sunny days and warmer temperatures, now’s the perfect time to say so long to the weight room and take things outside. And why not head straight to the shore to work on your beach body? Apart from the beautiful views and mood boost from spending time in the sun, your muscles will have an extra challenge stabilizing you in the sand. “Working out in the sand adds a ton of resistance to any exercise you’re doing,” says DailyBurn trainer Anja Garcia, who loves getting her sweat on outside when she goes on vacation. And HIIT (high-intensity interval training) is a natural choice for outdoor workouts because you can condition the whole body efficiently, without any equipment. This popular training method challenges your aerobic and anaerobic systems, meaning you’ll improve cardiovascular endurance and build strength at the same time. Plus, your muscles will work overtime blasting more calories than they would with just steady state cardio alone (also known as the afterburn effect).
