An exercising machine having improved control permitting either an assist or a resistance of the exercise being performed comprises a first member exercisingly movable by a part of the body against the resistance of a weight or spring and a second member operable by another part of the body with the second member advantageously comprising a pivotable lever, with a linkage selectively engageable between the second member and the weight or spring in two modes in which force applied to the second member in the same direction respectively assists and resists movement of the first member.

In order that the invention may be readily understood certain embodiments thereof will now be described with reference to the accompanying drawings in which:
FIG. 1 is a perspective view of one embodiment of machine,
FIG. 2 is a side view,
FIGS. 1-7 show an exercise machine specifically adapted for a bicep curl exercise. It should be noted however that the same basic chassis can be used for machines for other exercises such as bench press, lateral pulldown, tricep curl, forward leg press, shoulder press and many others.
The machine comprises a basic chassis 1 of generally triangular form supporting a seat 2 and inclined bench 3 having lateral arm support pads 4. Beneath the seat 2 are foot rests 5, and overhanging the bench 3 is an instrument bar 6 on which may be fixed instruments 7 such as a stopwatch, repetition counter and the like.
Depending from the sides of the chassis 1 are pivoted levers 8 mounted on a common axis. To the free end of each lever 8 is connected by a cable 9 a hand grip 10. Pivoting of the levers 8 in the clockwise direction as seen in FIG. 2 causes a pivotable load bar 11 with weights 12 to be raised by means of an interconnecting cable or connecting rod (not shown). The raising or lowering of the bar 11 can be assisted or resisted by pushing forward with the feet on the footplate 13 connected to a second member in the form of a pivotable lever 14 to be described more fully later. The footplate 13 is adjustably secured to the lever 14 by means of a locking shank 15 passing through a selected one of a number of registering apertures 16. By this means the user can adjust the footplate 1 to a comfortable position.
