When you do things TO the body and the breath, you might develop control of how you move and breathe, but you will be exaggerating the separation between yourself and your body. And separation is at the source of any physical/emotional issue you are using your yoga to redress...
Here I offer a clear and practical explanation of the difference between this, and relating to the world THROUGH your body and breath, which unites you with both. Follow my suggestions and feel the difference in yourself ... if you like the feeling, it will change your practice forever...

All of these things are to do with how we hold our weight up ... Here I show you how to become light, by giving your weight to to ground instead of to your back and joints... Enjoy!

Leg extensions - the way to do it that makes you want to do it all the time....

(plus my thoughts on Astanga)

How to liberate the upper spine for the true 'yoga' experience of these extension postures.

The solution to tight hamstrings...
When your hamstrings are tight, it is usually because they are overly involved with your support strategy. Here I explain what might cause this, and then offer a practice that is very likely to lead to a completely different somatic experience of opening out the legs, together with actually being able to let go of the habitual hamstring resistance, so they can be 'stretched' without the usual problems that go with attempting to do this.

The best way to massage them, and how to do any kind of balance.

If you want freedom in your body, the feet are far more important than you might think. Here I explain why problems with knees/hips lower back (and the rest of you) might well be sourced in feet that have become dull.
I show you the best way to massage your feet. and then give you an experience of the difference between supporting yourself over your foot compared to supporting yourself WITH your foot. I then add some details so you can take it into something like tree pose.

Sitting and twisting is a simple enough thing to do, but are you interested in HOW you do it?
If you are someone with tight groins, you will pull yourself round with your groins; if you have lower back issues, you will probably be twisting from there, and if the uppers spine is stiff you will probably pull yourself round with your arms and neck. With a willingness to explore the 'how' of it, sitting twists can help you re-balance whole-body movements in a way that can relieve you of most common-place postural issues... (apologies - the sound is not that good, but the content is really transformational if you can follow it)

How to release the groins whilst using the legs (squat and happy baby)

Frozen shoulder, tight ham strings, stiff neck....

Does your back pinch in sphynx & cobra? That can disappear with a simple shift of perspective and intention (plus some quite intense work - which should feel pleasant to do)

Boat pose ... how to approach so that you don't end up creating problems for your hips and groins... (if you already have these problems - perhaps just engage with the approach until the posture feels possible)... Enjoy!

How to 'open the hips' when there is groin pain/damage (or if there is basically resistance from the muscles and tendons around the hips)

Do you get dead legs/feet, painful knees, hips/lower back when you sit for any length of time? Here's why, and what you can do to solve these very common problems.

"Applying the solutions isn't easy because it will be all so 'counterintuitive' - here is my response to someone that wasn't sure about the intensity involved...
I did say you might need to let go of the idea of it being relaxing to start with! You can relax when there's balance over your base and through your spine, but to start with it most probably won't be comfortable! ... because the tissue around bones and joints won't be used to the arrangement... If you can relax into a new balanced arrangement, the tissue gradually changes to accommodate, and once it changes it will become both relaxed and more comfortable... and you will be generally more aligned... hope that makes sense.
