The ultimate Plank App ! – 30 Day Plank Challenge. Review

I love using this App whenever I need a short period challenge! In only 30 days you will build up strength and have a fit tummy !! I really enjoy doing my planks with Marin as she is very supportive along the way and keeps you in a good spirit to achieve this goal. Highly recommend as the V2 is even better.
