## Abstract

An exercise bench for use by a person on a support surface includes a base member having a distal end, a proximal end, a top surface, and a bottom surf ace. A pair of opposing foot restraints is fixed with, and disposed above and laterally away from, the base member. A riser projects upwardly from the proximal end of the base member and includes a calf restrain trolley slidably mounted thereon. Two opposing calf restraints each project laterally away from the riser. The calf restraint trolley has a height adjustment mechanism cooperative with the riser. A base plate can be fixed with the bottom surface of the base member, and a U-shaped base extension having two legs extending away from the proximal end of the base member can be attached to the proximal end of the base member to inhibit tipping of the exercise bench during use.

## Claims

### Claim 1

An exercise bench for use by a person on a support surface, comprising:
a base member disposed on the floor and having a distal end, terminating in a proximal end, a top surface, and a bottom surface;
a pair of opposing foot restraints fixed with and disposed above the base member, each foot restraint projecting laterally away from the base member;
a riser fixed with and projecting upwardly from the proximal end of the base member at a lower end thereof;
a calf restraint trolley slidably mounted on the riser and having a pair of opposing calf restraints each projecting laterally away from the riser, the calf restraint trolley having a height adjustment mechanism cooperative with the riser and adapted to allow selective height adjustment of the calf restraint trolley on the riser;
a removably coupled U-shaped base extension having two legs extending away from the proximal end of the base member;
whereby the exercise bench is configured to allow, the person to position his back on the support surface with each of his feet under one of the foot restraints and with the calf restraint trolley height adjusted such that each calf restraint is positioned behind a calf of the person, the person may perform sit-up exercises.

### Claim 2 (depends on 1)

The exercise bench of claim 1 whereby the person may perform sit-up exercises while lying between the two legs of the U-shaped base extension.

### Claim 3 (depends on 1)

The exercise bench of claim 1 wherein the height adjustment mechanism includes a spring-biased pin having a knob at a proximal end thereof, the distal end urged into one of a plurality of height apertures formed in the riser, whereby the calf restraint trolley may be selectively positioned at a height of one of the height apertures by engaging the distal end of the spring-biased pin into a selected one of the height apertures.

### Claim 4 (depends on 3)

The exercise bench of claim 3 wherein the height adjustment mechanism is fixed on a proximal side of the calf restraint trolley centered between each calf restraint.

### Claim 5 (depends on 1)

The exercise bench of claim 1 wherein each foot restraint includes a padded cylindrical annulus.

### Claim 6

The exercise bench of claim l wherein each calf restraint includes a padded cylindrical annulus.
