Basic bicep curl

 How to: 

  • Hold a dumbbell in each hand and stand with your feet as wide apart as your hips.
  • Let your arms hang down at your sides with your palms forward.
  • Pull your abdominals in, stand tall, and keep your knees slightly bent.
  • Curl both arms upward until they’re in front of your shoulders.
  • Slowly lower the dumbbells back down.
