I use the same 4 machines...the incline chest press, leg press, shoulder press and this big thing that I hook up to make it like i'm rowing...*I forget what it's called*. I do this every other day. I do 4 reps of 15-25 for each machine. The whole workout takes about 1 hr 15 mins or maybe just a little longer.
I can still function afterwards....usually the next day I wake up and can really feel it in my arms. I have really strong legs and of course I walk off a lot of the pain so I don't have too much of a problem with leg pain. It basically just feels really tight and...well like it's been worked. I guess it's a good feeling?
I do love it....I just hate it when I'm doin it....especially the shoulder press...that thing KILLS me!
So as long as I'm not doing this EVERY day then I'm fine, right? Every other day is only about 3-4 days a week so I think that's about right for starting out. I know my trainer told me only 2 times a week, but...eh...I like going above and beyond.
That is how I've lost 30 lbs in 5 weeks!
