Tips » Weight Training
I'm going to start training my abs — should I begin with weighted crunches?
Weighted crunches are definitely not the key right out of the gate. Most people who jump on those prematurely aren't getting full quality out of their workout.
When you focus and contract your abs appropriately, you can workout for years without ever adding external resistance. I have yet to find a person who does weighted abdominal work, short of competitive bodybuilders, who actually perform a crunch or leg raise correctly to keep the tension on the abs.
