You should still work your abs and back for a strong, healthy body but you don't need special equipment to do it.
In a study commissioned by ACE, researchers found no differences in muscle activity for basic crunches, obliques and reverse curls than for exercises done on top-selling ab machines.
Conclusion: Don't waste your money. All you need is yourself and a floor (preferably clean). If you decide to get something, get an exercise ball...it's cheap, versatile and offers an excellent way to work your core.
