What Makes the Bowflex SelectTech 840 Different

The SelectTech 840 stands out from traditional kettlebells through its innovative adjustment system. You turn a dial to select your desired weight. The mechanism locks plates securely in place. This happens in just seconds.

Most adjustable kettlebells use pin systems or screw mechanisms. These take longer to adjust. The SelectTech 840 uses a dial system similar to adjustable dumbbells. You simply twist the handle to your chosen weight setting.

The weight range spans from 8 pounds to 40 pounds. You get six different weight options: 8, 12, 20, 25, 35, and 40 pounds. This covers beginner through intermediate training levels. Advanced users might want heavier options for certain exercises.

The design includes a flat base when rested. This prevents rolling and provides stability between sets. Traditional kettlebells often roll away during floor exercises. The SelectTech 840 stays put.

The handle diameter matches standard kettlebell sizes. Your grip feels natural during swings and presses. The weight distribution mimics traditional kettlebells once properly adjusted. You won’t notice major differences during most exercises.

Build Quality and Durability Assessment

The SelectTech 840 uses high-grade plastic and metal components. The outer shell feels solid but not indestructible. The adjustment dial mechanism contains the most critical parts. These need careful handling.

I’ve used this kettlebell for several months. The dial system still works smoothly. No wobbling or loosening occurred during normal use. The weight plates lock firmly when properly adjusted. You hear and feel a satisfying click.

The handle coating provides good grip. It doesn’t tear up your hands during high-rep workouts. Sweat doesn’t make it dangerously slippery. Some users apply chalk for extra grip during intense sessions.

The base shows minor scuffing after repeated floor contact. This is normal wear. Nothing suggests structural weakness. The kettlebell handles drops from waist height without damage. I don’t recommend dropping it from overhead positions though.

The adjustment mechanism needs protection during exercises. Ballistic movements like snatches put stress on the dial area. Using proper form reduces wear. The design handles standard kettlebell exercises well when you maintain control.

Quality control seems consistent based on user reports. Few people mention receiving defective units. Bowflex offers warranty coverage for manufacturing defects. This provides peace of mind for your investment.

Top 3 Alternatives for Bowflex SelectTech 840

Weight Adjustment System Explained

The dial selection system makes weight changes simple. You place the kettlebell on a flat surface. Turn the handle dial to your desired weight. Lift the kettlebell and unused plates stay behind in the tray.

Each weight setting locks with an audible click. You feel resistance when the dial reaches a weight position. This tactile feedback confirms proper engagement. Visual indicators on the dial show your selected weight clearly.

The transition between weights takes about 5 seconds. This beats unscrewing collars or moving pins. Your workout maintains momentum. Circuit training becomes more practical with quick weight changes.

The mechanism works reliably when you follow proper procedure. Forcing the dial causes problems. Gentle, deliberate turning keeps everything working smoothly. The system requires the kettlebell to rest on its base during adjustment.

Exercise Performance and Versatility

The SelectTech 840 performs well for fundamental kettlebell movements. Swings feel natural and balanced. The weight distribution doesn’t shift during the arc. Two-handed and one-handed swings both work smoothly.

Goblet squats feel comfortable. The kettlebell rests properly against your chest. The handle width accommodates different hand positions. You can hold it close without awkward angles.

Turkish get-ups work fine with proper control. The adjustment dial doesn’t interfere when the kettlebell rests on your arm. Maintain smooth movements throughout the exercise. Avoid banging the dial against your body.

Cleans and snatches are possible but require care. The adjustment mechanism adds vulnerable components. These ballistic movements demand perfect form. Advanced users report success with controlled snatches. Beginners should master form with traditional kettlebells first.

Overhead presses feel balanced. The weight doesn’t pull forward or backward unexpectedly. Single-arm and double-arm variations both work well. The handle provides secure grip throughout the range of motion.

Rows, deadlifts, and carries all work excellently. These controlled movements put minimal stress on the adjustment system. The flat base helps with suitcase deadlifts. The kettlebell sits stable during setup.

Space Saving Benefits for Home Gyms

Traditional kettlebell sets consume significant floor space. A basic set of six kettlebells needs about 10 square feet. They scatter across your workout area. You constantly reorganize them.

The SelectTech 840 occupies less than 2 square feet. The included tray holds everything neatly. Your training space stays organized and accessible. This matters in apartments and small homes.

Storage becomes effortless. The kettlebell sits in a closet or under furniture. You don’t need dedicated gym storage. Moving it between rooms takes seconds. The compact design makes it travel-friendly too.

The aesthetic advantage matters for shared living spaces. One sleek kettlebell looks cleaner than multiple scattered weights. Your living room or bedroom stays presentable. Family members won’t complain about gym clutter.

Small home gym setups benefit most from this space efficiency. You can combine the SelectTech 840 with adjustable dumbbells and a bench. This creates a complete strength training setup in minimal space. Your entire gym fits in a closet.

Cost Analysis and Value Proposition

Individual kettlebells cost between 30 to 80 dollars depending on weight and quality. A six-kettlebell set runs 300 to 500 dollars. The SelectTech 840 typically costs around 200 dollars. The savings become obvious.

You get six weight options for less than half the cost of individual kettlebells. The economic advantage makes home training accessible. Budget-conscious fitness enthusiasts appreciate this value.

The cost per pound metric favors adjustable designs. Traditional kettlebells cost about 2 to 3 dollars per pound. The SelectTech 840 costs roughly 5 dollars per pound initially. But you’re buying 6 weight options totaling 140 pounds of capacity.

Long-term value depends on durability. If the adjustment system lasts several years, the investment pays off. User reports suggest good longevity with proper care. Bowflex’s warranty coverage adds value insurance.

Opportunity cost matters too. The money saved can buy other equipment. Resistance bands, a yoga mat, or a pull-up bar complement your kettlebell training. Building a diverse home gym becomes more affordable.

User Experience and Ease of Use

Setup takes about 5 minutes out of the box. The instructions are clear and simple. You insert the weight plates into the tray. Test the adjustment dial. Start working out immediately.

The learning curve is minimal. If you’ve used traditional kettlebells, you’ll adapt instantly. The adjustment process becomes automatic after a few uses. New exercisers find it intuitive and straightforward.

The dial occasionally requires attention during workouts. Checking that weights locked properly becomes habit. This takes seconds and ensures safety. A quick visual confirmation prevents accidents.

Maintenance requirements stay minimal. Wipe down the kettlebell after sweaty workouts. Keep the dial mechanism free from debris. These simple habits extend equipment life. No special tools or expertise needed.

The user-friendly design accommodates different skill levels. Beginners appreciate starting at 8 pounds. They gradually increase weight as strength improves. Intermediate users jump between weights for varied training.

Family use works well. Different household members select appropriate weights. Everyone shares one piece of equipment. This maximizes value for family fitness goals.

The noise level stays reasonable. Weight changes produce minimal sound. The kettlebell doesn’t clank during exercises when properly adjusted. Apartment dwellers won’t disturb neighbors during morning workouts.

Comparing Traditional vs Adjustable Kettlebells

Traditional kettlebells offer superior durability for aggressive training. They handle drops, throws, and intense ballistic movements. No adjustment mechanisms can break. This appeals to serious kettlebell sport athletes.

The feel of traditional kettlebells remains unmatched for some purists. The solid construction provides specific feedback during movements. Advanced users notice subtle differences in weight distribution.

Adjustable kettlebells win in convenience and space efficiency. The ability to change weights instantly transforms workout programming. Progressive overload becomes easier to implement. You don’t wait between exercises.

Cost comparison favors adjustable designs for home users. Commercial gyms benefit from traditional kettlebells. They serve multiple users simultaneously. Home gyms rarely need six kettlebells available at once.

The versatility advantage belongs to adjustable models. You experiment with different weights for new exercises. Finding your optimal training weight happens faster. This accelerates fitness progress.

Safety Features and Considerations

The locking mechanism provides the primary safety feature. When properly engaged, weights stay secure during exercises. The audible click confirms correct adjustment. Visual indicators provide secondary confirmation.

The dial design prevents accidental weight changes during use. You can’t twist the dial while holding the kettlebell in workout positions. This eliminates mid-exercise adjustment failures. The system proves reliable when used correctly.

The flat base prevents rolling accidents. Traditional kettlebells roll toward feet or under furniture. The SelectTech 840 stays put between sets. This reduces tripping hazards in crowded spaces.

Weight selection errors pose minimal risk. Choosing the wrong weight won’t cause equipment failure. You simply stop and readjust. The process takes seconds and prevents injury from excessive weight.

The handle design includes no sharp edges or pinch points. Your hands stay safe during weight changes. The smooth surfaces prevent cuts and scrapes. This matters during long training sessions.

User responsibility remains critical. Proper form protects both you and the equipment. Dropping the kettlebell onto the dial mechanism can cause damage. Controlled movements extend equipment life and prevent injury.

Maintenance and Longevity Tips

Clean the kettlebell after each workout. A damp cloth removes sweat and oils. This prevents buildup on the handle and dial. Regular cleaning extends the life of all components.

Inspect the adjustment mechanism monthly. Look for cracks, loose parts, or unusual wear. Address small issues before they become problems. Bowflex customer service helps with replacement parts if needed.

Store the kettlebell in its tray when not in use. This protects the adjustment dial from impacts. Keep it away from extreme temperatures and moisture. A dry, temperature-controlled space works best.

Avoid dropping the kettlebell unnecessarily. Place it down with control after each set. This simple habit dramatically extends equipment life. The adjustment system lasts years with careful handling.

Lubrication isn’t typically necessary. The factory lubrication lasts for normal use periods. If the dial becomes stiff, contact Bowflex before applying any lubricants. Improper lubrication can attract dirt and cause problems.

The weight plates need occasional inspection. Check for cracks or damage. Damaged plates should be replaced promptly. Using damaged components risks injury and further equipment damage.

Who Should Buy the SelectTech 840

Home fitness enthusiasts find tremendous value in this kettlebell. If you train at home regularly, the space savings and convenience justify the purchase. You’ll use it frequently enough to maximize the investment.

Beginners and intermediate lifters fit perfectly within the weight range. The 8 to 40-pound spectrum covers most exercises for these levels. You can progress for months or years before outgrowing it.

People with limited workout space benefit most. Apartment dwellers, dorm residents, and anyone with small homes need space-efficient equipment. The SelectTech 840 solves the storage problem elegantly.

Budget-conscious buyers get excellent value. The cost savings compared to individual kettlebells make quality kettlebell training accessible. You build strength without breaking your budget.

Families sharing equipment appreciate the adjustability. Each person selects appropriate weights for their fitness level. One purchase serves multiple users with different needs.

Your workout area stays organized and uncluttered. The compact footprint makes home training practical in limited spaces.

You might pair it with heavier traditional kettlebells for comprehensive training.
