Bat Weights

A bat weight adds resistance to your bat during warm-up and training swings. It helps hitters loosen up before their at-bat and build strength in the hands, wrists and forearms over time.

A donut bat weight is a round, weighted ring that slides onto the barrel of your bat. It’s the classic on-deck warm-up tool, like the Rawlings 16 oz Doughnut Bat Weight or the Franklin 16 oz Bat Weight.

Yes. Donut bat weights slide over the barrel of most baseball and softball bats, including wood, alloy and composite models, and rest on the taper above the handle. Make sure the weight fits snugly so it doesn't slide during warm-up swings, and always remove it before stepping into the batter's box.

• Light weights (5 to 10 oz), like the Easton 5 oz Speed Training Weight, Rawlings Hit Jack 9 oz or Easton 10 oz XL, are best for younger players and for keeping swing speed.

• Standard weights (16 oz) are the most common on-deck choice for teen and adult players.

• Heavy weights (24 oz), like the Rawlings 7" Pro-Style Bat Weight, are for strong adult players focused on strength training.

When in doubt, choose lighter: a weight that’s too heavy can change your swing mechanics.

A bat weight helps warm up and strengthen the muscles used in your swing. Many coaches recommend taking a few swings with your regular bat after using a weight, so your timing and feel are back to normal before you step into the box. For speed-focused work, try a lighter weight like the Easton 5 oz Speed Training Weight.
