Post a picture of yourself with the cover of your book!

Put @fitgirlsguide and #28dayjumpstart in the caption of your post (or #fitkinibodychallenge or #fitgirlsbootcamp depending on the challenge you are doing this round). Tip: have a friend take it for you while you hold up your device!

Meet other girls who are doing the program by finding their book cover posts in the hashtags. Then keep posting throughout your journey! We recommend posting once a day to keep yourself accountable. Your Instagram must be public to participate in the prizes (optional). Most girls create a Fit Girl Instagram account.

Challenge goes from March 13th - April 9th.



We're giving out (15) $100 Amazon Gift Cards to awesome Progress Photos! Participating in the Progress Photo prizes is not required to join the challenge. It's just for a little extra fun and motivation.


If you want to be eligible for the prizes, check our @fitgirlsguide Instagram page on the evening of Friday, March 10th. We'll announce a phrase you need to hold in one of your before pics. (For example, last month it was "#iamthemothership".) This is how we make sure everyone is using pics from the same weekend and keep things fair. Your pictures will not be eligible if you do not have a picture in your before clothes holding this message. You must be 18 or over to be eligible for prizes. Pictures that are selected for prizes will be featured on the @fitgirlsguide Instagram page the week of April 10th.


Before & After pics will be submitted HERE by April 10th 11:59PM PTS. We will post details about how to submit pics on April 7th to our @fitgirlsguide Instagram page. Please do not email your pictures.

We also highly recommend posting your progress to your Instagram profile to share them with the community!

Use the #JumpstartProgress hashtag.


The Fit Girls Books are manuals for a lasting, healthy lifestyle. They are not a crash diet. We will not consider Before & After pictures that suggest you went to unhealthy measures to achieve your results. Please also read the Terms of Use for details.

We will choose a variety of body types for our prizes to represent the variety of women who participate in our program. You are welcome no matter where you are in your Fit Girl journey! Prizes are just our way of giving back to the community and spreading a little fun around. The real prize is your healthier lifestyle and fitness progress!
