"Run" from your chair and you'll not only get a nice cardio boost, you'll also engage your abs, arms, and legs (plus, this may be the safest way to run in heels!).
How to do it: Sit with legs extended, toes pointed, arms bent by sides. Brace abs in tight and hinge back until just shoulder blades are lightly touching the back of the chair, lifting legs low in front of you. Bend left knee into chest, turning right shoulder in towards knee, pulling left elbow slightly back, then quickly switch sides. Repeat as quickly as you can for 30 alternating reps.
Don't be fooled: This workout firms and burns much more than you'd think!
