Thank you for this course. I've just finished with week 5 (which is the week I've started with), and I've made quite a bit of progress which I'm very happy about. It's really a great structured program - and it's very exhausting!! Wow

However, I have one thing, that is limiting myself - the mobility of the back of my hamstrings, I just cannot extend both legs at the same time.

This means: In week 5, the leg warm-up - exercise, both of my legs (the one on the ground and the one in the air) are bent.
In week 6 there's even more exercises that are affected: The straddle mobility exercise, I manage to get an angle of about 60 degrees between my legs - not even close. And also the exercise with the chair - I just cannot extend the leg in the air at all, it stays bent - which I think defeats the purpose.
Are there any exercises you can recommend to mobilise/stretch them (I understand it won't be something I can fix in the short term) or variations of the exercises that are easier for me?
Thank you and kind regards
Flavio
