Physical training systems that may promote effective technique and strength training for various sports, as well as general strength and fitness training. Apparatus may require a user to push and lift in a coordinated manner to effectively overcome inertia and rolling resistance. The training apparatus may include a cylindrical core portion and compliant outer portion located on an outer surface of the core portion. In use, the training apparatus may rotate around a center axis of the core portion when a sufficient force, exceeding a resistance level, is received by the training apparatus (e.g., as a result of a user exercising proper technique in applying force to the training apparatus). The resistance level may be a result of a configurable amount of ballast contained within the apparatus.

1. A training apparatus configured for a user to perform sports training exercises on a horizontal ground surface, the apparatus comprising: a rigid cylindrical core portion having a center axis, two end surfaces substantially normal to the center axis, and a circumferential outer surface extending between the two end surfaces, the core portion being hollow and configured to receive an amount of ballast via a resealable fill port positioned on one of the end surfaces; andan outer portion disposed on the outer surface of the core portion, the outer portion comprising a compliant foam portion and a protective cover portion disposed on the compliant foam portion, wherein the outer portion is deformable to have an area with a generally flat surface in contact with the ground surface, thereby providing a rolling resistance, and wherein the compliant foam portion is configured to deform in response to an impact by the user with the protective cover portion;wherein the training apparatus is sized having a height above a waist of the user when resting on the ground surface and is configured to roll about the center axis when the user uses his or her hands to contact the protective cover portion at or above waist level to exert a force exceeding a resistance level against the training apparatus from a stance in which the user's knees are bent, wherein the exerted force includes a horizontal component that pushes the training apparatus and a vertical component that lifts the training apparatus. 2. The training apparatus of claim 1, wherein the core portion is about 40 inches in diameter, and wherein the outer portion is about 6 inches in thickness. 3. The training apparatus of claim 1, wherein the amount of the ballast held in the core portion is user configurable. 4. The training apparatus of claim 3, wherein the resistance level is further based at least in part on a configurable amount of a filling material within the outer portion. 5. The training apparatus of claim 4, wherein the filling material within the outer portion comprises air. 6. The training apparatus of claim 1, wherein a height of the training apparatus is configured to be adjusted by varying a configurable amount of a filling material within the outer portion. 7. The training apparatus of claim 1, wherein the core portion holds the ballast and wherein the ballast includes sand;wherein an amount of the ballast is user-configurable;wherein the core portion is about 40 inches in diameter, and wherein the outer portion is about 6 inches in thickness. 8. The training apparatus of claim 1, wherein the core portion holds the ballast. 9. A method for athletic training, comprising: a user standing on a generally flat horizontal ground surface and positioning his or her hands at or above waist level to contact a protective cover portion of an apparatus resting on the ground surface to deform a compliant foam portion that is disposed under the protective cover portion;the user bending his or her knees and exerting a force exceeding a resistance level against the apparatus that causes the apparatus to roll across the ground surface, wherein the exerted force includes a horizontal component that pushes the apparatus and a vertical component that lifts the apparatus;wherein the apparatus is sized having a height above a waist of the user when resting on the ground surface and includes: a rigid cylindrical core having a horizontal center axis substantially parallel to the surface, two end surfaces substantially normal to the center axis, and an outer surface extending between the two end surfaces, the cylindrical core being hollow and partially filled with an amount of ballast via a resealable fill port positioned on the cylindrical core, wherein the ballast includes sand; andan outer portion disposed cylindrically about the cylindrical core, the outer portion comprising the compliant foam portion and the protective cover portion, wherein the compliant foam portion is deformable to have an area with a generally flat surface in contact with the ground surface, thereby providing a rolling resistance, and wherein the compliant foam portion is configured to deform in response to contact with the protective cover portion. 10. The method for athletic training of claim 9, wherein the resistance level is configurable. 11. The method for athletic training of claim 9, further comprising: adjusting the amount of ballast in the cylindrical core. 12. The method for athletic training of claim 10, further comprising the user lowering his or her hips prior to exerting the force. 13. The method for athletic training of claim 9, wherein the apparatus continues to present the resistance level as the apparatus rolls across the surface and the user continues to exert the force. 14. The method for athletic training of claim 10, further comprising: adjusting a height of the apparatus by varying a configurable amount of a filling material within the compliant foam portion.
