I'm a lazy person . But I want to build my body up , without going to the gym . Suggest me some good exercise routine to get those six packs ...
You to prioritise high tension low rep range over large rep range with lower tension.
The key in building muscle is something called 'Time under tension'.
A good number of reps for hypertrophy (building muscle) is 8-12 whereas for building strength a good range is <6. You want to build muscle, not strength! (understand the difference :)) (A keynote is this: the abdominals are muscle, and need to be trained accordingly - e.g., they need the same kind of attention as any other muscle; tension > volume) (A second keynote: approiate tension is key, chose a weightrange where you fail after 12 reps.)
You also need to eat a solid diet, and a low (e.g. very low 6-10% BF, the lower you go the morw definition you get)
Lastly, there are no shortcuts - many (especially product advertisers) would have you believe this; this is false!!)
Visit a site like www.t-nation.com and read some articles - you'll have to educate yourself a little to reach your goal.
I believe theese are the keypoints to achieving a six-pack. Next up you'll have to research some exercises yourself. And remember, regular situps will not do much, the key is ToT (time under tension).. :)
Sorry bout the bad grammar also, was written in a rush.
