Ab Blitzing on the 5 day layer system for 3 weeks…an extra 15 min a day after the assistance work? Any over training issues here…just would be very tiring those 3 weeks I would say. Energy wise.
I always train my abs by 2-4 week blitzes. I do not do 15 mintues worth of abs work though. Normally I like to do one superset for abs (one weighted movement then one unweighted one) for 3-4 sets. This takes about 5-6 minutes.
