1 ) Machines are here to make working out easy for people who dont want to work out
2 ) Machines lead to more injurys because they isolate muscles and bodies loose muscular ballence
3 ) the only use for a machine I can see is rehab from injury (maybe)
4 ) woman tend to view them as less intimidating
5 ) people tend to view them as safer (myth see number 2)
6 ) they look fancy and therefore must work
7 ) they lure people in who do not know how to lift free weights (not their fault just never taught)
8 ) the biggest reason is people belive the myth of spot reduction.
I think thats the big ones for you.
