Was just wondering if everyone on here is from america or wheter theres any other countries on here? Im from England

I am 68 yrs old, have a small gym at home. I had a supraspinatus tendon partial tear 6 mm 3 years ago. After regular physiotherapy sessions the tear has reduced to 1 mm. It's healing.✊. Started working out again now I am doing all the exercises Keith is guiding through his videos. He always warns us about shoulders. Like that. My question: Can I use resistance bands for internal and external rotation excercise for shoulders ?

Had a shoulder tendon tear, 3 yrs ago. Better now still working out
