Overview
The Rogue JC-40 Jerry Can is a versatile, water-fillable training tool designed for Farmers Walks, overhead presses, squats, and lunges. Inspired by the classic metal cans used in early CrossFit Games competitions, this modern version is constructed from high-density polyethylene (HDPE), making it more economical, portable, and durable for everyday gym use. By using water as resistance, athletes benefit from dynamic weight distribution, which challenges stability and core engagement throughout each movement.

Performance Benefits
Active Stability: The "sloshing" of the water inside the can creates unpredictable weight shifts, requiring greater activation of the stabilizer muscles and core.
Functional Grip Training: The handle size and weight distribution make it an excellent tool for improving grip strength and endurance.
Unilateral Conditioning: Ideal for single-arm carries and presses to identify and correct strength imbalances.
Scalable Intensity: Easily adjust the difficulty by adding or removing water to meet the specific needs of different athletes or training cycles.
Maintenance and Care
Fill Material: Use water ONLY. Do not use sand, lead shot, or other solid fillers, as they can damage the HDPE shell when the can is dropped or placed down heavily.
Cap Management: Ensure the rubber gasket is seated correctly in the cap before tightening to maintain the leak-resistant seal. Avoid over-tightening.
Cleaning: Periodically empty and rinse the interior of the can to prevent the buildup of bacteria or mold. Wipe the exterior with a damp cloth and mild soap.
Storage: Store the cans in a cool, dry place. Avoid prolonged exposure to direct sunlight or extreme temperatures, which can affect the integrity of the plastic over time.
