Rachel’s story

Rachel Sheffrin: body transformation testimonial

Rachel is a 36 year old mum of 2 who works full time 5 days a week. When she came to BTX she struggled with a skinny fat physique, had no idea what she was doing in the gym, and was stuck in a cycle of under eating and bingeing. In just under a year of working with BTX, Rachel achieved a defined mid section she had been missing since her first pregnancy, built a solid nutritional baseline so she would never fall for fad diets again, and became a female role model for her 2 daughters. This is what genuine, sustainable body transformation looks like.
