The exercise Kelvin Gary, personal trainer and founder of Body Space Fitness in New York City, swears by is the kettlebell swing. “This move is a great way to get your heart rate up while at the same time working your backside, your hamstrings, and your core.” See more beginner-friendly kettlebell exercises here.
Try It: First, you’ll need a kettlebell. Start with on that is 10 to 15 pounds (4 to 6 kilograms) if you’re a beginner, 15 to 20 pounds (6 to 8 kilograms) if you have experience with them. Now to the swing: Stand with feet shoulder-width apart, gripping the kettlebell with both hands. Bend knees, then hinge at hips to swing kettlebell between legs. Stand as you swing it to chest height.
