1. Train Heavy
Training your abs with heavy weight will enable them to grow and press up against your skin. Doing hundreds of sit-ups or crunches does not always prove effective. Your abs can actually respond effectively better to heavier weights and lower reps than higher reps. Level Up Your Abs With These Tips
2. Take Time To Rest
The abs are just like every other muscle group. They need proper rest and recovery, or you will risk overtraining and hindering your progress…You wouldn’t train chest everyday would you? Try to do abs no more than 3 times per week.
