It is a well known fact that weight loss results only come with persistence exercise.
Experts recommend doing around one hour of exercise per day which should be a mixture of cardio and strength training.
It was revealed that Rebel works on high-intensity interval training, mobility, weights, resistance, technique and temp, with only one rest day per week.
“Wow…girl, you look fantastic…you’re inspiring! Work it, own it,” another fan commented.”
Rebel has previously spoken out about her body and explained she has struggled with her body image.
She told Cosmopolitan: “I love me some ice cream or desert, and it comes at times when I’m happy or sad.
“So when I have an incredibly stressful day, I want to celebrate and reward myself with food. If I’ve had a sad or stressful day, food is also comfort.”
However this year Rebel promised to herself that she would be sticking to a strict six day a week workout and would be ditching the comfort foods with healthy nutritious meals.
