Question: Is the slide board foldable?
Document: Even the most successful at home workouts I've tried include lots of high-impact sequences and I hate the idea of strengthening my heart and quads while damaging my knees and back. And by the way, it is not a feminine and it is not easy!If you're looking for a workout you can do with limited space that's different from things you've tried in the past I highly recommend the slide board.
I will update this review when I receive the new board and have had a chance to test it out.4-5-14 ADDITIONAL UPDATE:I finally received a brand new replacement slide board which does appear to be new and improved. The bottom plastic strips are now black and are thicker than the original strips. I tested the board and it does appear to be stronger and sturdier.
Just received the slide board and have not fully used. Did a 5 min tryout and noticed the board is not very slippery. I can use a bit more like the directions state and board may get better with time. My main problem is that as a person with long legs I am not sure if this 5' board is for me. I will give till next wk and keep trying to see if I can get past the length, if not I may have to return.
My legs are getting solo toned by this thing. Easy to get use to and you get great cardio workout. I would suggest it to anyone who needs a low impact exercise routine. There are many different muscle groups this board works out.
If other customers encounter cracked/broken strips, I hope they will immediately replace those strips with the new thicker black ones. It is an easy fix to replace the old strips with the new ones and the board itself is very good. The problem was with the parts used to attach the bumpers to the board.
Nicely made board and booties. I don't find the videos helpful because they don't utilize the board much. They generally involve floor work and hand weights(dumbbells).It does take awhile for the board to relax and unroll at the edges after storing it, but this would occur with any good material.So far I have not had a problem with the ends cracking as some people have mentioned. Handle them carefully when you unroll the mat.Good workout.
I bought this board because I owned one before (from a different company), but got rid of it because it was old. It's good for cardio and helped me stay in shape. The only thing I didn't like when I first got this board is that it looked used. It seems to me that the one I received was a returned from an unsatisfied customer. I didn't call to complain because it states in the instructions that the scratches and discoloring will go away with usage.
I was very happy with how I was treated and I will definitely buy a larger board once i graduate from the 5 foot length. I recently had knee surgery and I have had so much pain trying almost anything else. THIS IS THE BEST EXERCISE PRODUCT I HAVE EVER USED AND I WOULD RECOMMEND THIS PRODUCT WITH ANYONE WITH KNEE PAIN, OR ANYONE WHO WANTS TO GET BACK INTO SHAPE AFTER A LONG BREAK FROM REALITY.
This workout has completely changed my life. I am stronger and I now can run long distances much easier than before. I can see changes in my body that I haven't seen with other workouts. I would recommend this to anyone.
This is definitely a new workout that is fun to do. You can definitely feel it in your legs and crotch area when you first start using it. The only reason I am giving this 2 stars is because the sides cracked immediately and we have been unable to get a hold of Obsidian to get a refund/replacement. Amazon won't refund/replace because the box has been open. My husband has taped and super-glued the sides, so hopefully it won't crack too much more.
Answer: yes
