Hi lovely,
Most of our workouts are lower impact so you should be fine. The only workouts that could cause problems with your knees are running and HIIT. You can substitute running with power walking (just make sure it is a flat surface because an incline will bulk up your legs) and do workout that are not HIIT training.

Hi lovely,
Thanks for reaching out! :)
If you dedicate yourself to eating healthy, doing your cardio and exercising, yes you definitely can! Rachael’s program is a full-body program that will help you slim down your legs and upper body, lose belly fat and tone your whole body without adding any unwanted bulkiness. It lasts for 8 weeks and it includes a cardio plan, resistance training with short demonstration videos, and 2 meal plans with recipe ebooks (vegan and regular one).
When it comes to fat loss, we all have some unhealthy routines that we could substitute with some healthy ones, it is all a matter of having a plan and sticking to it. xx
Love,
Tina
