Yes it's a commercial gym. i use that machine because sometimes the only person is there, is a very skinny instructor girl, so i don't trust that she can help me if i get a power loss.

so i leave the legs day for when there is a male instructor, and i can do heavy liftings because i know if i need help he will assist me.

but like i said previously i don't use machines all the time, i usually use free weights
