I purchased the "8 pack deal" which includes: Getting Started, Getting Stronger, Get Rolling, Volumes 1,2,3 & 4, Boot Camp. (promo code VFROCKS for 10% off). I was actually going to also purchase the "Ultimate Horizontal Club DVDs Vol 1" (24 workouts), but Sandra talked me into maybe waiting until the 25% off Fall Sale (September-ish).
So far I have done Getting Started Workout #1 and #2 (both 10 minutes). I did one yesterday and one today (recommended not to do on consecutive days, but I felt fine).
I am really glad I got the WAGs Ultra gloves - my wrists did not hurt at all and they usually do during plank work. However, the inside of both gloves have a seam from the external wrist strap that is a very harsh jagged seam and both of my wrists are cut up. I am going to have to stuff some material or cotton down there to prevent this.
My thoughts on the Getting Started workouts (remember, I have only done the first 2 workouts) are - I like them! I consider myself an advanced Cathe exerciser, but my abs are probably my weakest part. I do have a pretty strong core just from the fact many of Cathe's workouts build up the core in non-traditional ways.
While I did not find the HC workouts particuarly hard, I did find them challenging. I was able to do all of them and even made my own modifications to make them harder (she does have a helper in the video showing an easier modification for each workout). I definitely felt the burn, but was able to complete each exercise. The first 2 workouts I did were a lot of push-ups and plank work. I kept feeling my abs during the exercises and they were rock hard, so I know I was hitting the right spots.
I really think this 1st workout is good for beginners or advanced exercisers. It is nice she has modifications to make it easier and the 10 minute timeframe is nice to be able to do just once or multiple times.
I also felt my arms getting a good workout from just holding in the plank position. I am doing Volume 1 on Friday - I believe it is almost an hour long. I can write my thoughts on that if anyone is interested.
