Lat Sweep
If you're at the gym, you can perform this exercise, also known as the Lat Sweep, on a cable machine. However, it's simple to do at home as well. There is even a variation you can perform at work. Take your resistance band, for example, and fasten it to a doorframe. The next step is to extend your arms out and hold them just below chest height while standing far enough away from the door so that the band is snug when you grab both handles.
In addition, you begin in that position, holding your lower body and chest steady as you sweep your arms down to your sides while maintaining a straight back. Raise them back to the starting position gradually. Do 15 reps after that. You may perform a similar exercise on a table by sitting down, placing your hands on the surface, extending your arms in front of you, and bracing your core while you press into the table. You have to truly press down and contract your abs to feel this very slight exercise. Repeat for 15 reps, holding for one second before releasing.
