Abstract
The utility model relates to fitness facilities, in particular to a portable counter-pulling spring chest expander which comprises a guide rod support, a sleeve support, tension springs, handles, guide rods, sleeves and fastening screws. Two parallel guide rods on the guide rod support are matched with two sleeves on the sleeve support, and the guide rods can move in the sleeves. The fastening screws are arranged on the sleeves and control locking of the guide rods so as to control the guide rods not to move in the sleeves. The tension springs are respectively connected with the guide rod support and the sleeve support, and at the same time, two handles are connected with the tension springs. Arms counter pull the tension springs inwards to achieve different exercising effects compared with an existing spring chest expander. The supports of the portable counter-pulling spring chest expander can be contracted and extended, and the portable counter-pulling spring chest expander is convenient to carry and capable of achieving different exercising strength of people with different arm lengths. The portable counter-pulling spring chest expander can achieve different exercising strength through changing the amount of the tension springs.
Description
Technical field:
The utility model relates to a kind of health and fitness facilities, is a kind of portable to drawing steel strand exerciser specifically.
