Oct 26, 2021

Besides fighting the urge to over-decorate the house and eat all those sweet treats, one of the most challenging parts of Halloween is picking your costume!

There's plenty of options for superheroes, movie characters, and even foods that you could choose. But we made a list of our favorite costume ideas that will help you show off your love of fitness, your creativity and will have you bringing home that "Best Costume" prize!  

1. Strong Man 

Here's your opportunity to show off those gym gains you've been working on all year for! 


What You'll Need: 

  • A Muscle Tee, Tank Top, or Leotard
  • Sneakers
  • 2 Foam Balls - The larger they are, the stronger you'll look!
  • 1 Wooden Dowel
  • Glue
  • Black Acrylic Paint
  • Self Adhesive Faux Moustache

TIP: Remember when making your barbell to avoid using high-temperature hot glue guns and spray paint to avoid melting the foam!

2. A Kettlebell 

Transform yourself into one of the most iconic pieces of fitness equipment! Careful dressing up in this costume. You just might get picked up... *wink wink*
