One woman's journey doing Kayla Itsine's BBG program is proof that it's never too late to get fit!
While Instagram user @fitbyfifty.us provides the disclaimer that she has had previous fitness knowledge and made an effort in the past to keep close to her goal weight, she thinks that others can definitely get good results too.
"Progress using my #bbgguide!" she wrote. "I really never thought I could get in shape from working out from home until I started the @kayla_itsines program . It's been fun, challenging, eye-opening and definitely rewarding! Yes these photos are 15 weeks apart and no, they are not tampered with or photo shopped.
"This is 15 weeks of working out 3x a week, 15 weeks of doing 30-45 minutes of cardio (#LISS) 6x a week and 15 weeks of eating clean, healthy low fat, nutritionally balanced meals 3x per day ... 6 1/2 days per week . Yes, I allow a cheat meal or two one day a week ;)"
She has posted updates throughout her BBG journey, and aims to lose another 5 pounds (2kg) to reach her goal weight.
