Hi,
As i am new here and the first message that came up was to either introduce myself or ask a question, i am choosing the second one although i am not sure if the threads has to be grouped. Please correct me if i am wrong.
I was wondering if someone can help me find out what kind of system class the following exercises are:
1) knee extension
2) bench press
3) squat with and without external weight.
Thank you in advance.
Regards.
