So im at my gym doing my thing today mostly just farting around on the tredmill because I started Christophers routine in the middle of the week and I dont want to get super serious about it until monday where I can really go at it. Anyways im noticing my gym has about a 50/50 split when it comes to free weights versus machines. I know most if not all of yall lift with free weights so you can work your stabalizers. That being said since I have no work out partner and I wanted to find my max on like bench or squats could I get a accurate number from the bench press machine/leg press machine? Is there a disadvantage other than stabalizers to useing machines?
