A device for exercising producing limited strain on the back. The exerciser is supported on a base which also provides a mounting surface for an upright. The upright supports a leg rest where the exerciser's legs are placed during use. With legs elevated on the leg rest the exerciser does sit-ups. Attachment of the leg rest to the upright is done in such a way that it may be disposed at a plurality of heights for adjustment to the user's needs. To vary the exercise difficulty the angle of inclination of the platform may be adjusted either when used in conjunction with other exercise apparatus or when used alone with use of the appropriate attachment. psc:fenwick;patents
