The Blazer Medicine Balls are a versatile strength and conditioning staple that works for every sport on your campus. The rubber-compound outer shell has a textured surface for a secure grip during throws, slams, and rotational work, and because these balls float, they double as a resistance tool for water workouts. Training with a medicine ball builds core strength and stability as the torso works to control its center of balance through every movement.
- Durable rubber-compound outer shell with a textured, easy-grip surface
- These balls float — great for pool and water workouts
- Builds core, rotational, and total-body strength for all sports
- Seven weights available: 1K/2.2 lb and 2K/4.4 lb (195 mm), 3K/6.6 lb and 4K/8.8 lb (228 mm), and 5K/11 lb, 6K/13.2 lb, 7K/15.4 lb (275 mm)
- Ideal for individual workouts and team circuits
Coach's tip: start athletes with a lighter ball to groove clean mechanics on throws and slams, then progress the weight as control improves. Wipe the balls down after use and store them indoors away from direct heat to protect the rubber shell.

From $217.95
The Gill PowerMax Weight Vest adds adjustable resistance to running, jumping, and strength work so athletes can build power and conditioning with a natural range of motion. A stretchable neoprene strapping system secures the vest to the body while allowing it to expand and contract with your normal breathing pattern during exercise — keeping the load stable without restricting the athlete through hard efforts.
Key features & specs:
- Stretchable neoprene strapping system holds the vest securely while flexing with your breathing
- Holds double-stitched 1/2 lb shot-filled weight packets for fine resistance adjustment
- Add packets to build the short vest up to 20 lb (long vest scales higher)
- Short vest (TA1226): fits up to a 40" chest/waist; 18" long x 16" wide; 2-3/4" shoulder straps with 5-1/2" of adjustment
- Long vest (TA1227): fits up to a 57" chest/waist; 23" long x 16" wide; 2-3/4" shoulder straps with 5-1/2" of adjustment
- Adjustable shoulder straps dial in a secure, custom fit
Coach's tip: Start light and add 1/2 lb packets gradually — small increments let athletes keep clean mechanics while progressively overloading sprints, jumps, and bodyweight circuits. Care: Remove the weight packets before washing the shell, wipe down after sweaty sessions, and store the vest flat so the straps and neoprene keep their shape.
$179.95
The PowerMax V2 Medicine Ball is built for the way teams actually train — throws, slams, rotational work, and partner passing that demand a ball that grips well and holds its shape. Its textured polyurethane shell gives athletes a confident hold even through sweaty, high-rep sets, while expert construction keeps the ball balanced and dimensionally stable rep after rep. At 14 inches in diameter, it's a versatile core-strength and power-training tool for athletes across every sport.
Key features & specs
- Grippy, durable shell — 18 oz. flexible, moisture-resistant polyurethane cover textured for a secure grip
- Quality construction — Hand-sewn casing and expert ball build for long-lasting performance
- Consistent feel — Dimensionally stable and balanced, maintaining its impact-absorbing properties over time
- 14" diameter — Sized for rotational throws, slams, partner passing, and core work
Coach's tip: Use it for rotational wall throws and overhead slams to build the explosive core power that transfers to swinging, throwing, and jumping. Care: Wipe down after use, keep away from abrasive surfaces, and store at room temperature to protect the shell.
$119.95
The PowerMax Swing Ball adds a dynamic, rope-handled dimension to your strength and conditioning program. Built for swinging, slamming, and rotational drills, it lets athletes generate and control momentum through the hips and core — training the explosive rotational power that fuels throwing, swinging, and change-of-direction movements across sports. The attached nylon rope and handle give athletes a secure grip for controlled arcs, overhead swings, and ground slams alike.
Key features & specs
- Designed for swinging, slamming, and rotation drills
- Rope: 1/3" nylon with a 30" handle measured from stopper to rope end
- Diameters: 2K = 7.5"; 3K, 4K, and 5K = 9.5"
- Color-coded for fast, easy weight identification
- Versatile tool for power, core, and rotational conditioning
Coach's tip: Use the swing ball for rotational slam variations to build the hip-to-shoulder sequencing that transfers directly to throwing and hitting sports. Always clear a wide, unobstructed area before swinging. Care: Inspect the rope and handle attachment before each session, wipe down after use, and store hanging or coiled to protect the rope.
$69.95
The PowerMax Non-Bounce Medicine Ball is purpose-built for explosive throwing, dropping, and slamming drills — the movements that develop power, core strength, and full-body coordination. Unlike a standard medicine ball, its dead, non-bounce design means it stays put where it lands, so athletes can rep out overhead slams and rotational throws without chasing a ball rolling across the gym. That translates to safer, higher-tempo training and more quality reps in every session.
Key features & specs
- Designed to be thrown, dropped, or slammed without bouncing or rolling away
- Dead-ball response keeps the ball where it lands for fast, safe reps
- Durable PVC construction built to absorb repeated high-impact use
- Ideal for slams, rotational throws, and overhead power work
- Works for individual training and team conditioning circuits
Coach's tip: Use the non-bounce ball for max-effort slams and chest throws against a wall or floor — the dead response lets athletes go all-out without recoil. Care: Wipe the PVC shell clean after use and store indoors away from extreme heat to keep the material supple.
From $44.95
The Gill PowerMax Rubber Medicine Ball is a versatile strength and conditioning tool built to hold up across every sport and setting. Made from durable synthetic rubber, it stands up to daily use indoors and outdoors, making it ideal for weight rooms, field work, and team conditioning circuits alike. A color-coded system makes weight selection fast and foolproof during high-tempo sessions — athletes and coaches can grab the right load at a glance without hunting for stamped numbers.
Key features & specs
- Durable synthetic rubber construction suitable for all sports
- Rated for both indoor and outdoor use
- Color-coded by weight for fast, easy identification
- Weights marked in kilograms
- Available sizes: 1k = 6.5" dia, 2k = 7.5" dia, 3k = 9.10" dia, 4k = 9.5" dia, 5k = 10.5" dia, 6k = 11" dia
Coach's tip: Build a set with two or three weights so athletes can progress loads through the season and run partner passing drills across ability levels. Care: Wipe down after use, avoid prolonged exposure to extreme heat, and store out of direct sun to preserve the rubber shell.
$54.95
The PowerMax Grip Ball is a versatile weighted training tool built for power development, throwing work, and rehabilitation. The built-in rubber handle sets it apart from a standard medicine ball — athletes can grip and throw it single-arm or double-arm, sidearm, underhand, overhand, or heave it for full-body power. That handle opens up swinging and rotational movements a traditional ball can't do, making it a favorite for throwers, rotational-power athletes, and athletic trainers guiding controlled rehab progressions.
Key features & specs:
- Built-in rubber handle for grip, swing, and throw variety
- Throw single-arm, double-arm, sidearm, underhand, or overhand
- Great for power throws and controlled rehabilitation work
- Durable rubber shell with weighted filler
- 8" ball diameter; handle measures 1" x 1¼"
- Won't harm rubber gym floors or weight-room surfaces
Coach's tip: Use the handle for rotational throws against a wall to build the hip-and-core power that transfers to throwing and striking sports. Care: Wipe the rubber shell clean after use and store indoors away from temperature extremes to keep the shell and filler in good shape.
$49.95
Keep your athletes progressing with the Gill PowerMax Weight Vest Additional Weight Pack; 5 lb. Progressive overload is the foundation of strength and speed development, and this add-on pack lets coaches increase a PowerMax Weight Vest's resistance 5 pounds at a time — no need to buy a new vest as athletes get stronger.
Key features & specs:
- Adds 5 lbs of supplemental resistance to the PowerMax Weight Vest
- Designed specifically to fit and attach securely to PowerMax weight vests
- Distributes weight evenly for balanced, comfortable training
- Lets coaches customize load without replacing the vest
- Ideal for speed, agility, and strength-development programs
A smart, budget-friendly accessory for high school athletic programs and trainers building out weighted-vest training. Add packs gradually as athletes adapt to avoid overloading, confirm each pack is seated securely in the vest before every session, and store the packs with your vests in a dry space so they're ready for the next workout.
$169.95
Build functional, full-body strength with the Gill PowerMax Sand Bag Kit; 80 lb. Adjustable, shifting, and versatile, sandbag training develops the stabilizing strength and grip athletes need on the field — and this kit gives coaches a durable, scalable tool for everything from carries and cleans to squats and throws.
Key features & specs:
- Set includes inner and outer bags, holding up to 80 lbs total
- Leak-proof inner bags each hold 20 lbs of sand securely (sand not included)
- Inner bags are pre-marked for easy, accurate load measurement
- Five strategically placed padded handles for multiple grips and lifts
- Adjust total weight by adding or removing inner bags for progressive training
A rugged, adaptable addition to any high school or club strength and conditioning program. Fill the inner bags to the desired marked weight and seal them before loading the outer bag, inspect the handles and seams regularly for wear, and store the kit in a dry space to keep the sand contained and the bags in top condition.
