Allright so..My problem is..that i have abs..and they are pretty strong..but i just can’t see them.I guess they are not toned..or something like that..My abs look like a hamstring :D..it might be my diet or something like that..so here are some details..My workout is mainly sprinting..i do little squatting or crunching exercises..but i still do them..its just not that often..as i said my main workout is sprinting and some freerun..cause i have fun doing them..unlike weight-lifting..or some cardio exercises which are boring as hell..i can feel my abs burn almost everytime i sprint..and they hurt too..which means that they are getting ripped..and i know that they are pretty strong..but my problem is with them being visible.Things i eat alot..(i mean like everyday)..are carrots,bananas,apples,eggs,greek cheese,whole grain bread,peas,tomatoes,etc..so if you know a solution please share it with me :D..
Try doing more crunches, sit ups, leg lifts, etc. Remember though that you need something like under 15% (I seem to remember under 10%, but i dont know for sure) body fat to have abdominal muscles that are visible under your skin, so it may be incredibly difficult to do this. You probably could do it though if you work out enough.
Also, are you sure that when you sprint that pain in your abdomen is actually your abs being worked and not a cramp? I thought that sprinting only worked your legs and made you skinny, but im not a trainer
