Sit Ups Can Get You A Great Six Pack...
WORKOUT MYTHS...
Myth: Sit-ups are the best way to get 6-pack abs
Truth: Sit-ups or crunches targets only your abdominal muscles and strengthens just a few muscle groups.
Unlike planks, which use several groups of muscles along your sides, front and back.
If you want a strong core, especially the kind that would give you 6-pack-like definition, you need to challenge all of these muscles and look very carefully at what you eat
