Choose any solid and stable surface and crank out a set of 5-10 pushups. The sink, counter, desk top, back of a chair, hood of your car, park bench, all provide great surfaces to add fitness into your day. The key is to maintain good posture with your back straight. Here are a few progressions if you’re looking for variations:
Lift and hold one foot up off the floor.
Slow your pace to allow a 4 second count when lowering and pushing.
Add in a 10 second plank hold in between each rep.
Lift and hold one leg out to the side of your body.
Hold the pushup for 5 seconds when your arms are bent.
Extend your elbows only half way up when pushing.
*Consult your physician before beginning exercise.
