Indoor walking- Can you recommend a FREE programe.

Just that really.
I've seen various ones on Instagram and Facebook but you have to type in all your details before they tell you the cost, (if they tell you the cost without hiding some charges).
I also want to work on my core strength so would appreciate recommendations for that too.

Thank you.

Walking with Leslie Sansone on YT is good - very american and enthusiastic! GrowwithJo is good if you want additional moves and her music is good. GetfitwithRick is good - nice back drop, bright and sunny - could be Dubai.
