Exercise apparatus

A resistance band for strength training, comprising:

• a first cable being elastic and elongate and having opposing first and second end portions, the first end portion being configured to be grasped by a user, the first cable having a first elastic modulus;
• a second cable being elastic and elongate and having opposing first and second end portions, the first end portion of the second cable being configured to be grasped by the user, the second cable having a second elastic modulus that is different than the first elastic modulus of the first cable, each of the first and second cables being resiliently biased toward an unstretched length thereof such that the first and second cables resist being stretched in response to an application of a tension force to the first end portions thereof and respectively return to the unstretched length upon the user releasing the tension force;
• a first connector attached to the second end portion of the first cable;
• and
• a second connector attached to the second end portion of the second cable and configured to detachably couple to the first connector, wherein each of the first and second connectors includes a pair of male mating features, and a pair of female mating features configured for removable receipt of the respective pair of male mating features.
