a locking mechanism configured to selectively fix the press arm relative to the press arm support in one of a storage position and use a position, the press arm being closer to the upright member in the storage position, the locking mechanism configured such that the press arm can be moved from the use position to the storage position by (i) moving the press arm downwardly relative to the press arm support and (ii) rotating the press arm with respect to the press arm support, wherein the locking mechanism has a locked position and an unlocked position, wherein the locked position and unlocked position correspond to different positions along the first shaft, and wherein the press arm can move between the storage position and use position when the locking mechanism is in the unlocked position, and wherein the locking mechanism further comprises a biasing member engaging the first and second shafts urging the locking mechanism in the locked position.
9. The strength training device of claim 8 , wherein the locking mechanism further comprising a pin engaging both the first and second shafts in the locked position and disengaged from one of the first and second shafts in the unlocked position.
10. The strength training device of claim 9 , wherein the pin is disengaged from the first shaft in the unlocked position.
11. The strength training device of claim 8 , wherein a portion of the second shaft is positioned within the first shaft.
12. The strength training device of claim 8 , wherein the press arm support is pivotally secured to the upright member such that the press arm support is pivotable about a first axis and wherein the press arm is pivotally secured to the press arm support such that the press arm is pivotable about a second axis perpendicular to the first axis.
13. The strength training device of claim 8 , wherein the press arm comprises an extension pivotally secured thereto and having a portion for gripping by a user.
14. The strength training device of claim 13 , wherein the extension has a storage position and a use position, wherein the extension is closer to the press arm in the storage position of the extension than in the use position of the extension.
15. The strength training device of claim 8 , wherein said resistance assembly is selected from the group consisting of one or more weight stacks, one or more resilient rods, a rotation-activated resistance device, and a resistance mechanism having a pivoting arm and resistance member.
16. The strength training device of claim 8 , wherein said resistance assembly comprises a cable and pulley system and wherein the cable is selectively securable to the press arm support.
17. A strength training device comprising:
a frame;
a resistance assembly coupled to the frame; and
a press arm assembly comprising:
a press arm support pivotally secured to the frame and linked to the resistance assembly such that the resistance assembly resists movement of the press arm support, wherein the press arm support comprises a first shaft,
