Feeling lazy but still want to work your abs? Get on the floor and follow along to this intermediate core Pilates workout from Pilates teacher Isa Welly. You'll love her fun and vibrant energy, and even though this workout looks relaxing because it's all done while lying on your back (which makes for really smooth transitions between exercises), it's challenging. This workout is only 10 minutes, so it's quick, and Welly's simple instructions make it so easy to follow. This is a great way to get moving in the morning, or to tack on some ab work after a cardio workout. If you're looking for more like this, check out Welly's other Pilates workouts.
