Markwort Weighted 12-Inch Softball Set — 9, 10, 11 & 12 oz Leather Training Balls with Drawstring Bag

Markwort 12-Inch Softball Weighted Set is a four-piece leather training set with 9, 10, 11 and 12 oz balls designed to build throwing strength and improve mechanics through progressive overload.

Practice smarter by working up through incremental weights. This Markwort set includes four color-coded, leather-covered softballs sized for standard 12-inch adult play, plus a compact drawstring bag for storage and transport. Each ball is clearly marked by weight so you can plan progressive throwing sessions or tailor reps to skill level. These are recreation-type training balls intended for supervised use as part of a strength-and-mechanics program.

How will these weighted softballs improve my training routine?

Using progressively heavier balls lets you overload specific throwing muscles while repeating proper mechanics. The set's graduated weights let you increase resistance gradually without changing ball size, which helps preserve consistent release and grip patterns.

• Four weights—9, 10, 11, 12 oz—allow stepwise progression.
• Uniform 12-inch diameter keeps grip and release consistent.
• Leather cover provides realistic feel for throwing practice.
• Color-coded surfaces speed selection during workouts.

Are these balls durable and appropriate for regular use?

Each ball features a leather cover built for repeated throws in recreational training settings. Proper storage in the included drawstring bag and routine inspection will extend life, but avoid unsupervised heavy use or striking hard surfaces to reduce wear.

• Leather exterior resists abrasion in standard practice drills.
• Stitched seams resemble regulation softballs for realistic handling.
• Drawstring bag protects balls between sessions and eases transport.
• Not intended as guaranteed professional-grade competition equipment.

What safety and usage guidance should I follow?

Weighted balls increase resistance and require proper technique, warming up, and supervision to avoid strain. Use them as part of a structured program: start light, limit reps, and consult a coach for motion checks; discontinue if pain occurs.

• Begin with the lightest ball and add weight gradually.
• Perform dynamic warm-ups and maintain good throwing mechanics.
• Use under coach or trainer oversight, especially for young athletes.
• Seller disclaims warranties; user assumes responsibility for safe use.

How do I fit these into a training plan or drilling routine?

Integrate the set into short, focused sessions: warm-up, technique drills with the light ball, then limited heavy-ball sets for strength. Track load by counting throws and cycling days between heavy and recovery sessions to manage fatigue.

• Warm-up with mobility drills and the 9 oz ball for 5–10 minutes.
• Use the 10–11 oz balls for controlled mechanics and moderate resistance.
• Reserve the 12 oz ball for low-volume strength throws only.
• Store in the included drawstring bag to keep gear organized.

Who is this for: This Markwort 12-inch weighted softball set targets recreational players, coaches, and trainers who want a simple, graded way to add resistance to throwing drills. It’s suited for adult athletes and mature youth working under guidance who need consistent ball size with varying weights for progressive training. If you’re seeking regulation game balls, competitive-grade alternatives may be preferable; if you want a compact, leather-covered training set for arm-strength and mechanics work, this four-piece kit is a practical option.
