3a Crossover Push-up
Start to the left of a resistance band. Grab it and get in push-up position, far enough away that you feel light tension. Do a push-up. As you raise your torso, lift your right hand and pull the band across your chest. Place it on the floor, hold, then return to the start. That’s 1 rep; do 8 to 10 reps per side. After each set, without resting, do exercise 3b. Do 3 sets.
