The PowerBlock alternating dumbbell curl performed standing is a good exercise for bicep development. This exercise allows your body to move in it’s natural range of motion. Alternating arms allows for a short rest for each arm while the other is working so you can pump out a few more repetitions. Try not to use your body and cheat.


  • Standing with your body stabilized, hold the dumbbells down at your sides, palms facing your legs.
  • Keep your chest up and your elbows braced at your sides at all time.
  • Starting with one arm, pull the dumbbell up while turning your palm upward, then lower it.
  • Repeat with the other side.


  • Letting the elbows move forward instead of keeping them back against the torso.
  • Leaning back excessively.
  • Swinging the body.
