Necking..its all in your posture..and your chin..and your job..and and and and..

Your Shoulders & Neck...when you first start Pilates your TA is probably an unknown muscle to you and hasnt had a lot of practice bless it....(bet you know where your 6 pack is though, man or woman, this muscle is plugged and given Nos 1 billing in all the magazines..every bloke want to show off theirs if they can, and work it hard to make it more defined, but doing sit ups only gives you a bad back and neck pain..a tight 6 pack gives you a bad back, so see you at Pilates soon..but I digress as thats yet another subject.....)

Yes...where was I...Neck and Shoulders...After just one class you may not feel like you have relaxed shoulders, but you may be more aware of the muscles in that area and of the tightness you have, & by practing Pilates regularly, your tension will diminish and other muscles that are supposed to be working are strengthened to release your upper back & neck...strengthening your Latissimus Dorsi (Lats) releases Upper and Middle Trapezius tension. Your shoulder is the most mobile joint in the body...

Daily Neck stretches...easy does it though, (don't force it), help to release tension, stretch every hour if you work at a computer, or have a job that keeps you in an awkward position over the day (there are many...masseurs, chirpodists, doctors, nurses,hairdressers, primary school teachers etc etc)  strengthening weak underused muscles is the place to start & what we are aiming for.  
Forward Head Posture is very common, tuck your chin in, not too much so you lose your chin in your chest, just gently does it...retrain the deep neck flexors..think of your posture often, address it, look at yourself side on in a full length mirror, ear above shoulder? or is it far forward of your shoulder, knees locked, hips thrust forward, bottom tucked under? Not correct posture if youve answered yes..but thats for another day to address... its a big subject..
BUT...heres the crunch (get it?!) doing a class with 8 people in will not do it at first if you have a particular issue...you really need to start with a 1:1 or grab a friend and share the cost and do a Duet (a 1:2!) at your house, or come over to mine, or go to a Rehab or Gentle Pilates class(we do these on a Wednesday morning,if you cant make it ask for another class to be set up, we can look into other times!)
You will have time for a chat during the class, specific moves just for you, yes you will have to pay more, but then its always worth it as you get more out of it, you will progress quicker and then can go onto a class situation once you have the basics and know how to move without pain, tension, how to activate your T.A, how to activate your Lats, how to feel the release of tension and focus, concentrate on your shoulders melting down your back towards your Pelvis, release your tight Pec Minor muscles, they are small but do a lot of forward pulling on your shoulders, cheeky things.

Signing off with an image for you...imagine your head on a set of train tracks, move your head forwards on these tracks, your chin will point outwards, now bring your head back on those tracks, in alignment..think of doing this often, as you will forget and the chin will start to edge back out on those tracks again, take it back to the buffers..
