The portable collapsible exercise machine further includes a removable, adjustable T-bar arm member adapted to adjustably engage the first end of the first portion, and a removable, adjustable T-bar foot member adapted to adjustably engage the second end of the second portion. Removable resistance members adapted to engage the adjustable support member, the removable, adjustable T-bar arm member and the removable, adjustable T-bar foot member are also included. The second end of the first portion is hinged to the first end of the second portion at a point so as to allow the first and second portions to fold back onto one another into a collapsed position. ## Claims ### Claim 1 A portable, collapsible exercise machine comprising: (a) an adjustable support member having a first portion having a first end and a second end and a second portion having a first end and a second end; (b) a removable, adjustable T-bar arm member adapted to adjustably engage the first end of the first portion; (c) a removable, adjustable T-bar foot member adapted to adjustably engage the second end of the second portion, wherein the removable, adjustable T-bar foot member comprises an adjustable foot anchor that rotates about the adjustable T-bar foot member; (d) removable resistance members adapted to engage the adjustable support member, the removable, adjustable T-bar arm member and the removable, adjustable T-bar foot member, wherein the second end of the first portion is hinged to the first end of the second portion at a point allowing the first and second portions to fold back onto one another into a collapsed position. ### Claim 2 (depends on 1) A portable, collapsible exercise machine as claimed in claim 1 wherein the first portion is a padded back support member and the second portion is a padded seat support member. ### Claim 3 (depends on 2) A portable, collapsible exercise machine as claimed in claim 2 wherein the hinged point connecting the first and second portions, further comprises a series of attachment zones adapted to engage the removable resistance members. ### Claim 4 (depends on 3) A portable, collapsible exercise machine as claimed in claim 3 wherein the removable, adjustable T-bar arm member further comprises a series of attachment zones adapted to engage the removable resistance members. ### Claim 5 (depends on 1) A portable, collapsible exercise machine as claimed in claim 1 wherein the removable, adjustable T-bar foot member further comprises a series of attachment zones adapted to engage the removable resistance members. ### Claim 6 (depends on 3, 4, 5) A portable, collapsible exercise machine as claimed in claims 3, 4 or 5 wherein the attachment zones are pigtail loops. ### Claim 7 (depends on 1) A portable, collapsible exercise machine as claimed in claim 1 wherein the removable resistance members are further defined as resistance elastomeric tubing. ### Claim 8 (depends on 7) A portable, collapsible exercise machine as claimed in claim 7 wherein the elastomeric tubing provides resistance between 0 and 140 pounds. ### Claim 9 (depends on 8) A portable, collapsible exercise machine as claimed in claim 8 wherein the resistance elastomeric tubing has flexible handles at a first end and a flexible loop at a second end adapted to engage the attachment zones. ### Claim 10 (depends on 9) A portable, collapsible exercise machine as claimed in claim 9 wherein the removable resistance members further comprise safety socks encompassing the removable resistance members and secured to the first end and the second end of the resistance elastomeric tubing. ### Claim 11 (depends on 10) A portable, collapsible exercise machine as claimed in claim 10 wherein the safety socks are made from braided nylon tubing having a defined length secured to the first end and the second ends of the resistance elastomeric tubing. ### Claim 12 (depends on 11) A portable, collapsible exercise machine as claimed in claim 11 wherein the safety socks are UV resistant. ### Claim 13 (depends on 3) A portable, collapsible exercise machine as claimed in claim 3 wherein the removable resistance members are further defined as adjustable static arm bands having handles at one end and a flexible loop at a second end adapted to engage the attachment zones. ### Claim 14 (depends on 1) A portable, collapsible exercise machine as claimed in claim 1 wherein the adjustable support member can be adjusted into a 90° locked position about the hinged point by a lockable adjusting mechanism. ### Claim 15 (depends on 1) A portable, collapsible exercise machine as claimed in claim 1 wherein the adjustable support member can be adjusted into a 45° locked position about the hinged point a lockable adjusting mechanism. ### Claim 16 (depends on 1) A portable, collapsible exercise machine as claimed in claim 1 wherein the adjustable support member can be adjusted into a 180° locked position about the hinged point a lockable adjusting mechanism. ### Claim 17 (depends on 1) A portable, collapsible exercise machine as claimed in claim 1 wherein the adjustable support member can be adjusted into a 0° locked and collapsed position about the hinged point a lockable adjusting mechanism. ### Claim 18 (depends on 1) A portable, collapsible exercise machine as claimed in claim 1 further comprising a long bar with a first end and a second end and having removable resistance members at the first and second ends adapted to engage the adjustable support member.
