Sandbags

For general fitness and conditioning, start with 15-20kg. This allows you to perform cleans, squats, carries, and throws with good form while building stabilization strength. Women typically start at 10-15kg. Choose an adjustable bag so you can add weight progressively — jumping from 20kg to 40kg is too large an increase for most exercises.

Use play sand or builder's sand from any hardware store — it's cheap, consistent, and heavy enough. Avoid beach sand as it contains salt and moisture that promotes mold. Some athletes use rubber mulch or pea gravel for a different shifting pattern. Always place sand in sealed inner bags first, never directly into the main shell, to prevent leaking and make weight changes easy.

The key difference is instability. A barbell is rigid and balanced, while sand constantly shifts inside the bag, forcing your stabilizer muscles to work overtime. This builds functional strength that transfers to real-world activities like carrying groceries, moving furniture, or sports. The awkward shape also teaches your body to generate force from imperfect positions, reducing injury risk in daily life.

Yes, sandbags are excellent outdoor training tools. Quality bags made from Cordura nylon or ballistic fabric handle grass, dirt, and concrete surfaces well. Avoid dragging them on sharp gravel or rough asphalt, which can tear even durable fabric over time. After outdoor sessions, brush off dirt and let the bag dry completely before storing to prevent mildew.
