“The role of estrogen and progesterone receptors in the rotator cuff disease: a retrospective cohort study” BMC Musculoskeletal Disorders October 2021. Here are some snippets from the above article that I loved: - ER-ß showed the most significant association with tendon abnormalities. It implies that this receptor may play a leading role in altering tendon homeostasis compared to ER-a and progesterone receptors. - Hormone receptors in rotator cuff (RC) tendons is the first step to understand the potential role of estrogens and progesterone in predisposing shoulder injuries. -Immunoreactivity was seen in the nuclei of tenocytes and vascular cells. Postmenopausal women's samples showed a markedly higher expression of these receptors compared to their male counterpart. -In order to express their biological activities, female hormones have to interact with their specific nuclear receptors, estrogen receptor (ER) and progesterone receptor (PR). -There are two different isoforms of ER: ER-a and ER-B. - There are two progesterone isoforms: PR-A and PR-B. -Estrogen and progesterone are known to influence fibroblast proliferation and the production of type I collagen. -However, menopause is associated with an important reduction of type I collagen content in tendon tissue (the most important structural protein in tendons and ligaments). ——————————————— And when I say to you, you are primed for tendonitis in perimenopause and menopause, this is one of the reasons why you have changed. You are changing, we have to take of our joints. 11/15/2025

Estrogen receptors in your tendons!!!

See you tomorrow!!! Don't forget your muscles......moohaha

Recovery is one of the hardest parts of recovery for women to master... In my LIFT weight lifting program for women I do a whole video about avoiding injury and recovery because time and time again I see women I work with struggle to really prioritize this. The truth is recovery is the KEY that unlocks the benefits of training - so let’s make sure you know how to use it. This is why I had the incredible @drstacysims back on the Better Podcast to discuss all things hydration and recovery - we go DEEP. Cold plunging has become a hot topic in the last 5 years but we’re starting to understand more fully how to make it most effective for women looking to optimize recovery... For the full episode comment 433 and I’ll DM you the link. 11/04/2025

After 8+ years of working in this space and helping folks with weight loss, we don’t talk about weight loss much because talking about weight loss doesn’t actually help people. Talking about habits, behaviors, and helping people learn to value themselves and what they can do does. Follow us for content that feels helpful and welcoming rather than repetitive and scary. You are more capable than you think and deserve a kinder approach ❤️ #poweryourpotential #weightloss #glp1 #health #nutrition #fitness #resistancetraining 10/09/2025
