3. PUSHUP WITH RESISTANCE
Start in a pushup position, with your legs extended straight behind you and your hands shoulder-width apart. Position the band across your shoulder blades with tight resistance, each end tucked under a hand (a). Lower your body until your chest nearly touches the floor (b), then push back to start. That's one rep. Do 10 to 12.
4. FROG PUSH
Lie faceup, bend your hips and knees 90 degrees, and loop the band around your feet, crossing the band to create an X. Hold an end in each hand just above your shoulders or hips (a). From this position, brace your core and slowly extend your legs into the air straight in front of you (b). Pause, then return to start. That's one rep. Do 10 to 12.
