Bicep curls strengthen your biceps, making it easier to lift things during your everyday activities.
Start standing with your feet hip width apart with a light resistance band under both feet. If your band is long enough, you can hold either end of the band with each hand while the middle of the band is under your feet. If your band is not that long, you can stand on the end of the band and hold the other end with one hand.
You may perform this exercise sitting on a chair instead if you prefer.
Stand tall with your back straight and your lower abdominals engaged.
Bend your elbows and slowly raise your hands to your shoulders. Lower your arms all the way back down, staying slow and controlled the entire time.
