Question: Is it hard to raise yourself back up after being inverted. I am alone, 68 yrs old. I won't have help to get up once I am down
Document: I have a worn out disk at the #4 vertebrae. Almost completely gone and many times each year the vertebrae's slip just a little and I fall to my knees in pain and have a hard time moving. It takes days to get back into good shape. It is because the nerves in that area are being pinched. Have talked with surgeons and the only way to repair my back is surgery. I am 54 years old and I am just not ready for that kind of procedure in my life.
After inverting just one time the pain in my lower back disappeared. IT WAS AMAZING. I was able to walk upright for the first time in years without that same old pain. Just the other day I needed a little &#34;tune-up&#34; and inverted just one time. I felt like a new man. I have had several friends over to try this machine and they are all wanting to come over on a regular basis.
This was for my husband and he says it does help some. He has a very bad back at 80 years old and nothing could really change that in a dramatic way. He is glad to have found it and uses it faithfully. It assembled without problems and folds up compacting it somewhat when not in use. He believes it would definitely be of more help to individuals with less sever back issues and those of a younger age.
I love it. So far its great. I can get on and invert and feel my back loosening up right away. Works great after a long day at work standing and having my lower back knot up. My back will stiffen up and it's hard to bend over some times, this machine irons all the knots out.
I've been eyeballing these for a while and finally committed to buying one. So far very pleased with it. Had it about 2 weeks and i feel good when I get off of it. Takes a little getting used to though, first time I inverted, I couldn't figure out how to get back upright. Don't panic and you'll figure it out.
I have been inverting for short periods (less than a minute) about four times a day, after shower before work, when I get home, once during the evening and then before bed. I feel like a new man, I sleep better, I am moving better and my back is a lot less painful. I'm 45yrs old, 6'4" and about 220lbs, I have suffered from a painful back and sciatica since my mid-twenties but this table, well, this table has made a tremendous difference.
I have  trouble with my lower back and between my chiropractor and this machine it help a lot. Less is more when you use it. Maybe 3 or 5 minutes each use it. 2 to 3 times a day. You dint need full inversion. Very well built. Get the unit with the extended locking arm. Much easier to open the ankle lock. Good luck.
It is an easy and more importantly, safe way to get a full and extended stretch on the back...nicely decompressing and gently aligning your spine/back.Try it...it may just help you out!
absolutely love it! within the first use i started to feel the relief in my back. consult your dr first to make sure its the right thing for you. teeter is built extremely well - very solid. i looked at other brands in stores and they just don't compare. teeter is more expensive, but you get what you pay for. instructions also include a dvd to help step by step assembly.
There is a belt that comes with the package that can be attached to prevent full inversion. When fully inverted though, the pressure in the head is very high so it will take time to get used to it and to sustain the inverted position for any significant amount of time, i.e. more than 5 seconds.My kids use it, I suspect more so for fun. I use it for stretching.
Answer: yes
