Learn How The Four Body Types Determines A Celebrity Body Type Like Kayla Itsines
Celebrity Kayla Itsines shows off her genetic scientific Standard Body Type One (BT1) shape figure/physique 
while on holiday with her friends and family including her partner Jae Woodroffe. The candid images reveal no real signs of skinny fat (cellulite, thin fat, loose skin, saggy skin, crepey skin, normal weight obesity) anywhere on 
her body. The full development of her vertebra (posture) and muscles/muscle mass is currently not in debate.
Science recognizes that one pound of muscle burns six calories daily, but one pound of regular fat (white fat/yellow fat/excess fat) and/or skinny fat only burns two to three calories. Which directly affects metabolism (the more skinny fat and/or regular fat, the slower the metabolism) as well as body composition and shape. Having so many developed vertebrae, muscles, and muscle mass assists greatly in terms of metabolism/ metabolic rate (BMR), including aging gracefully.
Genetics/genes/DNA are important, but diet, exercise, metabolism, BMI, and lifestyle also matter. As she continues to age, it will be interesting to see how well Kayla Itsines maintains her body shape figure/physique. Is she really a genetic scientific Body Type Two (BT2)?
Kayla Itsines Figure/Shape – BT1
Star personal trainer and social media Influencer Kayla Itsines displays her Body Type One 
shape/figure during her time off. Her professional fitness and entertainment career began at the age of 18 after she 
graduated from the Australian Institute of Fitness as a Master Trainer. Paying her dues, she worked at a women’s gym in Adelaide where she came to realize that many women want three specific results from exercise — smaller inner thighs, flatter abdomens, and more toned arms — without becoming too bulky. With a growing following interested in her fitness and nutritional expertise, she utilized Instagram to post before and after pictures touting her successes along with ebooks.
In 2013, she became a burgeoning entrepreneur as the founder and director of the company Bikini Body Training with ex-fiancé Tobi Pearce (CEO). The following year, the duo published their first two Bikini Body Guides which include her workouts as well as nutrition information from dieticians Julie Dundon and Anne Schneyder of Nutrition Professionals Australia. The guides boasted an affiliate program and have been downloaded over one million times. The overall strategy was aimed at women and not focused on weight loss or muscle gain. Instead, the goal was to create a particular look. Moreover, the 2015 launch of her meal-planning and workout app Sweat with Kayla hit the top spot within its first year and subsequently generated more revenue than any other fitness app in 2016.

Body 28-Day Eating and Lifestyle Guide. Her second book, The Bikini Body Motivation & Habits Guide, dropped in 2017. She currently has nearly 28 million followers on Facebook, 16 million on Instagram, 85K on TikTok, and 41K on YouTube. Kayla Itsines’ demanding fitness responsibilities help with maintaining her body shape figure by increasing her metabolic rate thus burning more calories to keep excess regular fat weight at bay. As well, Time magazine named one of the 30 most influential people on the Internet in 2016.
Her estimated net worth is $63 million. She is active on social media including Facebook, Instagram, YouTube, and TikTok. See more personal fitness trainer, author, entrepreneur/businesswoman, and star social media influencer Kayla Itsines celebrity Body Type One (BT1) photos on Google.
