Hey guys !
Sometimes at the end of my training , i do a single set of abs wheel ' 30 reps'. or sometimes some set of 10 reps.
But i'm just wondering if i should do it more frequently.
It is really a hard exercice , i can just do it on my knees easily, stand up i can but i feel its hard yet for my lower back. just 2-3 reps i can.......
What do you think about this exercice ? usefull ? useless ?
because i find this guy very strong
Perform it with only one arm and stand up , its just AMAZING , need a huge amount of strength !!!!!!!........
Do we can build really a strenght with this exercice ?
thanks guy
