Hey guys: I'm a skinny fat middle age guy who (right now) is extremely weak (see log if interested) but who is determined to get stronger. I'm on 5/3/1 and have Rippetoe's Staring Strength book. I'm beginning to see that advancement on the (Military) barbell press and Squat is going to require a much stronger core, and my core right now is way too weak.
I don't have a lot of ideas for assist moves to build core strength, but I found a copy of my gf's Oxygen Magazine and it suggests the following to build abs: roman-chair sit ups , reverse crunch on a bench, bench crunches, and knee tucks (done sitting across a bench).
Will this work? Any other suggestions for assistance core exercises or lifts?
Great site. Thanks.
