Some days are tough. Work, travel, kids (hey, they need you) can add up to no time left for a workout. Or, that’s what you probably think. The truth is, you can squeeze in a workout that hits your major muscle groups, as well as your core. No equipment needed. You might even be able to fit them in before you leave the office. It’s okay, nobody’s looking.
Planks and pushups
Spend five minutes alternating between planks and pushups for an intense core (and arm) workout. Just keep your abs tight and tucked, and your breathing steady.
Square your hips, take a big step forward, place your hands on your front thigh, and slowly lower your body until your back knee hovers just above the ground. Don’t let your front knee extend past your toes. Push up from the heel of your front foot until your back leg is almost straight, then repeat. Then change legs.
Place your hands on your hips, keep your abs tight, take a big step out to the side and lower your body toward the ground. Keep the opposite leg straight and pull up through that leg. Do 15 on each side and repeat.
