No equipment? No excuses. Jada Pinkett Smith, 48, proved that you can still get in a full-body workout while quarantining with just a towel and slippery floor. Facing the floor, Jada positioned herself on top of a short towel with her stomach, hips and shins slightly raised, which the Girls Trip star demonstrated in a video that she shared to Instagram on April 13. Just think of how you’d execute a half-pushup!
