Input: Consider Input: A Good Introduction To Stability Ball . Swiss ball basics is a 50 minute workout , there is only 10 exercises which are performed in 2 sets of about 10 reps , the instructor shows more advanced variations on the second set and does some stretches in between the sets. Though the exercises can be challenging , the workout is pretty slow paced and let you to concentrate in the exercises. The quality of this video is very good and it is filmed on a sanded area , the instruction is very good also and during the exercises there's some animated pointers. I think if youre in a good shape you'd be better off just buying his "swiss ball abs" it has most of the exercises from swiss ball basics but it has 3x20 minute workouts in different levels (but there all pretty tough).

Output: POS

Input: Consider Input: Very Impressive DVD . I had always wanted to try Pilates, but was intimidated by the thought of actually trying some of the exercises that I've seen people doing. I hurt my left knee 3 years ago and have a hard time walking and sitting for any length of time. Well, I had a hard time. I have been using this dvd for 2 months now, and can do all the beginner's exercises, even the ones I thought I couldn't do. I was pleasantly surprised at the enjoyment and sense of well-being that I get from the program. The instructor is laid back, pleasant, and offers helpful hints. You can actually see what she is doing at all times, and she explains things very well

Output: POS
