The ZenZu Ball that arrived was perfect! I have an stability ball from Target but I have to fill it up weekly because it kept losing air so I was interested to see how the ZenZu Ball would do. My ball from Target is also flimsy. I will admit that I did not use the hand pump that came with the ball, instead I used a low flow air compressor. I filled it up and refilled it about two days later once the creases flattened out. I haven't had to fill it again! The ball also came with a little tool to help get the plug out so it is much easier to fill up. The ball is perfect. The ball came with a sheet of additional strengthening exercises that can be done with the ball. I haven't tried them all, but the exercises I have done are working well at strengthening my arms, legs, and core. The ball is available for $24.99 from Americas Nutrition and worth every penny!
America's Nutrition also sent me a Premium Yoga Mat by Zenzation. You have no idea how much easier doing a mountain climber stretch is when you have a yoga mat! One of the main stretches in the mountain climber is downward dog. My hands no longer slip here and there! Another benefit is that the mat is 1/4" thick. I do most of my exercising in my basement on the poured cement floor and the 1/4" thickness is a life saver. It is enough cushioning so that I am not hurting after I do my stretching and strengthening. The dimensions and other details of the mat can be found here. I have not taken the mat to a yoga class yet because of my current student teaching schedule, but I plan on trying it out as soon as I can. This yoga mat can be purchased for $23.99 from Americas Nutrition.
I recommend you try out their site and if you have questions contact them. They were very helpful when I was deciding what to try and always answered my questions in a timely manner.
