@RangerX Honestly this is the best advice anyone could ever give you for issues like mild thoracic kyphosis (granted there isn't any contraindication for it).
To help ameliorate APT you have to focus on your hip flexors/iliopsoas, which are also covered by many workouts in Darebee specifically made for this issue.
Regarding the LPT, especially considering the other issues you mention having, it is worth pondering if this is just a postural or muscle imbalance issue, or if there is something pernicious causing all of the aforementioned issues as a whole (injury/trauma, scoliosis, neuromuscular conditions, degenerative conditions, structural anomalies, etc.)
If that's the case, you are better off going to a physiotherapist and a doctor to investigate your specific needs.
It is unrealistic to expect a fitness program aimed at a diverse general population to tailor itself to these specific clinical needs; that falls outside the scope of such a program.
As users of a free resource, it is our own responsibility to manage our specific health limitations and seek professional guidance when a general program isn't the right fit.
Let’s keep the focus on the resource as it is intended to be used -and supported-.
