The main question here is do you have the will power to push yourself? A fitness trainer gives you support and variety, these are things you can do yourself. I know that sometimes it is hard to motivate yourself into exercising, so see if your friends are in the same boat. You will find you will push each other into working harder. There are numerous routines on the web or P90X is an excellent program at a fair price that covers everything. Plus P90X motivates you to workout, if those around you don’t want too. The bands don’t take up a lot of room and are resonably priced. They give an excellent workout.

You can use things around your house as alternative fitness machine things :)
like the step up things, you can just walk up and down the stairs.
Of course you can achieve the same level of fitness, the trainer is really to guide you and motivate you, so if you can find some way to motivate yourself, then you should have no problem.

Hope I helped. Good luck :) x

Yes.
But a PT will know things you won’t which will bring change and gains.
Any tips or help, just e-mail me.

I believe that a good home fitness workout can be, in almost all cases, more effective than going to a gym.

There’s just something about working out at home that makes it much more comfortable for me. I really don’t enjoy working out with sweaty old men breathing down my neck, waiting for the next machine to be open.
