Hi Annette,
You inspired me to reach for a kickboxing workout this morning. I chose Cathe's Rock'em Sock'em.
There needs to be independent research done on some of Cathe's workouts because they actually make me feel happy when I am doing them. Could Cathe's workouts help increase joy? I think so! What a fun workout. That said, Hard Strikes is my all time fav! fun fun fun!
have a great day.
