| When can situps make a difference?
I've often read that if you're obese, then situps don't really help tone your abs until you lose a bit of weight.
My question is this, I'm now about 20 lbs over the upper limit of my ideal weight. So, do you all think doing situps and other ab exercises will help me tone up my abs, or do I still need to lose more weight? Thanks. |
