text: do you have to go to gym to get a good workout? i have a treadmill, so if i continue to jog or walk on it, will it do good for me? or is going to gym the best answer?? nope.  but i will have to say that you will probably need to be more motivated if you intend to work out at home.  i tried trial memberships at gyms..and they are great for working out with a partner and if you want to use the machines.  there are pros and cons for working out at home and the gym.  however, if you do not have much money, you can easily work out at home.  you can do pushups and bodyweight squats..or run or jog.  those do not require any equipment at all!  i got a bench, barbell, and some dumbbells..those are great workout for weight training.  for cardio, you can run/walk or maybe get a treadmill or stationery bike (which i use).  or use those cardio tapes to get motivated like tae-bo (which is a tremendous workout). the only problem with working at home is that you do not have the environment and advanced machines as gyms do to work out.  but, it is inexpensive and just as effective.   in fact, i have not signed up for a gym membership at all and i have gained about 20 lbs of muscle (home-grown).    good luck!
