A golf club (20) having a club head (22) with an interchangeable shaft (40) is disclosed herein. The golf club (20) includes a tube (44, 144) mounted in the club head (22), and a sleeve (46, 146) mounted on a tip end (50) of the shaft (40). The tube (44, 144) includes a tapered portion (60, 160) and a rotation prevention portion (62, 162). The sleeve (46, 146) has a frustoconical portion (72, 172) and a keyed portion (74, 174) that are respectively received in the tapered portion (60, 160) and the rotation prevention portion (62, 162) of the tube (44, 144). The golf club (20) further includes a mechanical fastener (48, 148) for removably securing the shaft (40) to the club head (22).

An exercise system is provided in which multiple exercise routines may be conducted with a single system. The exercise system may be used for skiing exercises, rowing exercises, and for weight training / resistance exercises. The exercise system may also be stored in a compact position and may by integrated with articles of furniture for space saving benefits. In one embodiment, resistance to motion is provided by one or more tension transmission members and may be selectively adjusted by controlling the configuration of the tension transmission member relative to a torsion spring. Use of intermediate devices between the spring and the tension transmission member are described that provide a non-linear relationship between force and displacement. In another embodiment, the tension transmission member may be configured in different positions by adjusting the position of movable pulleys, thereby allowing the device to be used for a number of different exercise routines.

Golf club 2 has shaft 6, head 4, inner member 8 and cap 10. The head 4 has hosel member 22, and this hosel member 22 screw member 26 formed on the outer peripheral face thereof, and hosel hole 28. The cap 10 has screw member 40 formed on the inner peripheral face thereof, and internal extending portion 44 that extends more inwards than this screw member 40. The screw member 26 of this cap 10 and the screw member 40 of the hosel member 22 are bound by thread connection. The inner member 8 has shaft channel 46, and engaging face 50. The shaft 6 is stuck to the shaft channel 46. Engagement of the engaging face 50 with the internal extending portion 44 controls upward displacement of the inner member 8 with respect to the hosel hole 28.

An exercising apparatus for allowing mobility recovery and slimming activities. The apparatus is an endless belt-like exercising sport mat device which comprises a) an endless belt padded with a relatively soft and elastic material for serving as a sliding sport mat; b) a rolling mechanism for allowing the endless belt to be looped at a relatively low speed around the rolling mechanism, thereby providing a lower belt section and an overlying upper belt section on which a user may perform such activities; c) a supporting surface disposed under the inner surface of said upper belt section supporting relation thereto and depressible therewith under the weight of a user for aiding the user to move the endless belt; and d) a rigid frame for containing the supporting surface and the rolling mechanism.
