How can you get great abs without going to a gym and spending all that money?
Well, here where i live if you don’t have Abs you overall are fat. Even if your not. I’ve really wanted them. I just need tips to get them without spending so much on a gym.

get crunching/ab exercises off the net. also just doing crunches will help, and flexing ur muscles while doing just about anything.
Stomach crunches. Start with something you can manage, maybe 10 or 15 per set, then increase by 5 per set every week or fortnight.
Push ups are also not a bad idea, if you do them right, so you’re not just caning your arms.
If you are tired of the conventional crushes then I would suggest trying out the Ultimate Body Press Dip Bar. http://ultimatebodypress.com/ultimate-body-press-dip-bar.html
I too wanted to avoid the gym and the cost of a membership and I absolutely love this piece! It’s nice to be able to workout in the comfort of your own home and this dip bar is so light weight and portable it’s so easy and simple to store away.
I’ve seen great results in terms of toning my stomach and arms. Perfect for getting ready for summer!
Hope this helps!
