It is so fun that you are participating in the squat challenge! If you have any questions make sure to ask in the Food Fitness Finance and Fun Facebook group… if you have it, probably lots of people have it and are just afraid to ask!!
There are some products that I recommend in the group that have really helped me with my squats!
