Thanks for your comment!

Congrats on overcoming your hormonal imbalances. The endocrine system really can affect the bodies metabolism of energy. I am so happy you are experiencing improved energy levels.

You are correct by engaging the core during climbs. The more we resist movement in the lumbar spine, the better we transfer the energy from the legs to the direction we desire to move in.

From what I can gather, your weight loss and ’revival’ of your thyroid are where the majority of your fitness gains are coming from.

I hope that you will see continued progress in your exercise endeavours! Best of luck.
