Hamstrings are tricky and have a mind of their own.
I'll be 52 next month, have a pretty intense workout schedule, lift five days a week and at least walk five days a week. Stretched my right hammy a litttttttle too far doing RDL's and immediately caught myself, stopped and waited for the pain.
It never came.
Next time my leg rotation came up, that hammy said "Nope... not today, bruh" and continued that for like a month. I could do hyperextensions fine and get a bit of a stretch there if I focused on it. I could do leg curls and be fine as long as I kept the weight down and the reps up. A month later, the pain all went away.
Then it snuck up again and said "Yo."
Keep in mind I don't feel it at all daily, I'm not an athlete and I don't have access to the resources they do... and I'm in my 50's LOL!!! I'd give Lattimore a break. Hammies can be tedious to heal and unpredictable. My guess is he's doing what he can, but really needs the offseason to be 100%.
