An exercise system comprising:

• a bi-directional cam device comprising a housing;
• dual cam-type engagers secured within said housing and positioned in opposite bias, said engagers having a friction surface and being positionable between an open and a closed position;
• and means for securely holding a strap threaded into said device against said engagers when said engagers are in a closed position;
• a strap comprising means for securely affixing said strap to a non-moving surface, said strap being configured for slideable placement across said engagers of said bi-directional cam device when said engagers are in an open position;
• a resisting element configured for attachment to said bi-directional cam device;
• and
• a handle attached to said resisting element.

A method for securing cargo, comprising:

• providing a plurality of housings, each housing adapted to receive cam-type engagers, said engagers being positioned in opposite bias, having a friction surface, and being configured to pivotably move between open and closed positions within said housing;
• providing means for securely holding straps threaded into said housings against said engagers when said engagers are in a closed position, such that said straps are secured against movement relative to said housings when pulled in either direction across said engagers;
• placing said straps across a cargo load;
• threading said straps into said housings and across said engagers;
• and
• cinching said straps across said engagers to secure said cargo.
