Abstract: This leg press exercise machine is comprised of a single movable foot-plate arranged to move up and down a vertical path for exercising one leg at a time. It is designed to be used in the standing position. A controlled weight resistance mechanism is connected to the movable foot-plate for providing adjustable resistance to movement. At least one hand rail is positioned to aid entry to and exit from the machine and to stabilize the user while exercising. A lumbar pad (or backrest) is positioned to provide counter stability while exercising. A selector lever arm is used to select a maximum range of movement of the foot-plate. This selector lever arm can also be used to help leverage-up the leg to a position from which it is about to start exercising. The foot-plate is dynamic on its horizontal axis to reduce stress on the exercising foot.

Abstract: This multi-abdominal exercise machine is comprised of at least one foot-bar arranged to move up and down a vertical angular path for exercising the abdominal muscles otherwise known as the rectus abdominis. It is used in the sitting position. A controlled weight resistance mechanism is connected to the said foot-bar for providing adjustable resistance to movement. A seat that tilts up and down during the exercising movements together with and on the same axis as the foot-bar. At least one adjustable hand bar is positioned to aid entry to and exit from the machine and to stabilize the user while exercising. A dynamic back support is positioned to provide a contra, massage and stability while exercising. A method for using the abdominal exerciser is comprised of sitting on the dynamic seat, putting one's feet onto the foot-bar and lifting the knees towards the stomach. The said lifting causes the abdominal muscles to exercise, which effect is enhanced as the said seat moves.

Abstract: This squat exercise machine is comprised of a dynamic seat connected to a dynamic foot-plate where the weights are used to counter the weight of the exerciser and thereby assist him to raise himself from a squatting position to a starting sitting position. The squat exercise machine exercises the thigh muscles otherwise known as the quadriceps and the buttock muscles otherwise known as the gluteus group of muscles. At least one adjustable hand bar is positioned to aid entry to and exit from the machine and at least one handle to help to stabilize the user while exercising. A method for using the assisted squat exerciser is comprised of sitting on the dynamic seat, and with the aid of gravity, allowing the body to lower towards the floor whereupon the legs will be in a squatting position. With the aid of the weights, the thigh and gluteus muscles lift the seated body to its starting sitting position.

Abstract: This rowing exercise machine is comprised of an inclined seat with a weight resistance mechanism attached to handles for providing adjustable resistance to hand and arm movement. At least one hand rail is positioned to aid entry to and exit from the machine and to stabilize the user while exercising. A method for using the rowing exercise machine is to lie on the inclined seat, hold onto the weight resistance handles and pull down the said handles towards the direction of the user's body. The handles are then controllably returned to their starting position and the exercise is repeated as desired.

Abstract: This dorsal flex exercise machine is comprised of a static seat connected to the frame of the said machine. There is a foot-plate pivoted approximately under the position of the heel, when feet rest on the said foot-plate. The upholstered cylindrical lifting roller pads, one for each foot, are lifted by the upper side of the foot, lifting the said roller pads simultaneously. The said roller pads are adjustable vertically to fit the range of peoples' feet and shoe sizes. The dorsal flex exercise machine exercises the shin muscles otherwise known as the tibialis anterior muscles. The movement performed by use of this exercise machine is called the dorsal flex. At least one hand bar is positioned to aid entry to and exit from the machine and to stabilize the user while exercising.

Abstract: This combined chest press and leg press exercise machine is comprised of an inclined seat with a weight resistance mechanism attached to handles and a foot-plate for providing adjustable resistance to arm and leg movement. At least one hand rail is positioned to aid entry to and exit from the machine and to stabilize the user while exercising. A method for using the chest and leg exercise machine is for the user to sit on the inclined seat, hold the weight resistance handles and place his feet on the weight resistance foot-plate. He then pushes with his hands, the said handles forwards, away from the direction of the user's body. Simultaneously, he pushes with his legs on the said foot-plate also away from the direction of the user's body. The said handles and the said foot-plate are then controllably returned to their starting position and the exercise is repeated as desired.

Abstract: An exercising and training machine mainly for the abdominal part of the human body, and for building the abdominal muscles where reciprocating forward and back movement are performed against the power of an hydraulic piston.
