It’s Better to do a set routine for a while, so your abs get stronger and then once it starts to feel like a routine, it’s time to change it up and try something different. Then when that gets easy, go back to the routine. I have been doing the same routine for 20 years, off and on. It always works and I try different options once in a while, but I always go back. I’m in my 50’s and I still have a six-pack. That’s because the best way to get abs you can see is to stay lean. Once you have them, abs will always be easy to get back. The problem is “they go into hiding when you gain body-fat” Don’t forget the real core, the transverse abdominals! Plank away.
1. Abs are made in the kitchen.
2. Abdominal area is the first and last place the body stores energy (fat). It is not a link to how many crunches one does but a total body fat percentage indicator.
The best way to hit it is work all of the big muscles and work the abs like any other muscle. 3-5 sets max, 6-20 reps max.
