@davidasinclair I fractured my femur in a bike race a year ago. The psoas was the last muscle to come back and is still not fully recovered. My PT said you cannot isolate it to make it come back sooner. True?
@altini_marco just listened to a podcast with highly credentialed cardiologist. He explains how HRV is subject to breathing and that most monitors can't accurately measure it (bad paraphrase). Would love to get your thoughts. https://t.co/4PEfmfrTkf
@Alan_Couzens@BiggestComeback HRV high yesterday and completed hard 3x15 threshold session. Today HRV is low(normal after hard session) and I plan a one hour Z2 session. Yea or nay?
