OP, i was thinking for a while about switching from gym to home, only recently i made the decision, and i'm currently trying to pick out the most suitable equipment.
You say your not sure if your fully committed, well from my experience a bad gym environment can do this to you. It's hard to stay focused and motivated when your gym sucks, has lousy equipment and the people going there simply bring the place down.
Fair enough i understand people saying man up stick to it and find some excersises. But we can all do with some sort of motivational help, how many of you guy's have benefited from switching gym environments to something like PTC? You never know you might setup a good gym in your garage and find some locals nearby and get a good after work gym thing happening with some people who will motivate you and help you long the way and get you through.
I feel i will be more focused at home for a few reasons. No more arriving at the gym to find the bench, rack ect is taken up, and your either waiting around or end up doing something different. You don't always want to ask to work in either with others, whether they be heavier / lighter lifters, or just the type of people you don' want to work out with.
Also when i do get your equipment to myself, i'm often mindful of others and limit my time on it. At home i can spend as much time (and rest time between sets as i want)
I'm actually quite motivated at the thought of being able to work out at home and put in %110 as aposed to some of the half arsed workouts i've done at the gym due to limiting factors.
