Question: I am 64 years old.  can this product build up my calves at my age?
Document: The slant board is great! My son is 8 yrs old and uses it as part of his physical therapy. His doctor recommend that I have one custom made, and gave me specs for someone to build it for him. However, the one the doctor wanted him to use, you could not adjust the angle. Having one with with the option to adjust the angle has been great! The quality of the product is great, very well built! We are seeing great results with it.
slant board well made. Best of all this old lady is getting her legs back!!! I recommend this product for seniors trying to get their legs back into shape.
I started using a slant board several years ago when I inflamed the fascia on the bottom of my feet. The slant board was a vital tool that help me heal my feet. At first I hesitated  to purchase this slant board because of the price. Now that I have owned the product for over a year I believe that it was worth every penny I spent and I highly recommend it. The slant board is well made and adjusts to different heights.
This board is very effective. I have plantar fasciitis and use it to stretch my calves. I keep it under my bed and just slide it out at bedtime and in the mornings, or more often for a very effective stretch.
After a month of Physical Therapy the therapist suggested we get this slant board. He looked it up for me and I ordered it. My daughter (a 47 year old lady with Cerebral Palsy) and I (an 74 year old lady with a heal spur) use it every day to streatch heal cords and it does a great job. Thanks!! !
It is larger and heavier than I thought it would be, but that being said, it is built well, will not fall apart, will last forever. It has 5 positions for incline. I'm using the 2nd slot every morning and what a difference it has made for my calves.
Found the exercise in You Tube for patellar tendinitis which I have suffered from for years. I saw this board in Amazon. It is lightweight but sturdy and easy to clean and use. It even looks good in the room. The exercise on this board really works to control the pain of patellar tendinitis in just a few days. Highly recommended.
It was fantastic, durable, solid , met all my expectations. There is not a better way to stretch your calves or hamstrings
Sturdy, easy to adjust the incline, helps me stretch my calves out after sitting in a chair for work all day. My Physical Therapist suggested this, good for anyone.
Ever since I broke my ankle many years ago, I get frequent attacks of achilles tendonitis. I try to remember to stretch everyday, but I often forget and that's when the trouble starts. I saw this slant board at my physical therapist's office and it really helped me there. It's much better than just stretching against a wall. I bought it and placed it in my kitchen. Now, whenever I walk past it, it's there to remind me to stretch. So far, so good.
