Can you get a good workout from a crossbow machine? I noticed sears has them on sale for under $500 with intrest free for 6 months. Looked into get a bowflex a year or so ago and WOW they are expensive... Crossbow if it works looks like a better machine, its made by weider, I use to use their free weights and benches in HS. So what do you think of the Crossbow or Bowflex as a main workout machine? I had/have a Total Gym but it just made me dizzy sliding back and forth and up and down more than it gave me a workout. It was good for streatching though.
