About Barbells

A barbell is a type of exercise equipment used in weight training, bodybuilding, weightlifting and powerlifting. It consists of a long bar, usually with weights attached at each end, but can also be used without weights.

Barbells have a range in length from 1.2 metres (4 ft) to above 2.4 metres (8 ft), although bars longer than 2.2 metres (7.2 ft) are used primarily by powerlifters and are not usually seen in most gyms.

The central part of the bar varies in diameter from 25 millimetres (0.98 in) to 50 millimetres (1.96 in) (e.g., Apollon’s Axle), and is often engraved with a knurled crosshatch pattern to help lifters maintain a solid grip. Weight-plates slide onto the outer portions of the bar to increase or decrease the desired total weight. Locking Collars are used to stop plates from moving unevenly so that the lifter does not experience an uneven force.

The barbell is the longer version of the dumbbell that is used for free weight training and competitive sports, such as powerlifting, Olympic weight lifting, and CrossFit. Many exercises can be done using the barbell, such as bicep curl, bench press, Olympic weightlifting, overhead press, deadlift, and squat. Olympic barbells are usually an estimated weight of 20 kilograms (44 lb). Many fitness categories use the barbell for different reasons, for example, powerlifters use the barbell to perform compound exercise movements.

Bought a sled, turf and belt squat from NC Fitness. Service was great and build quality is good. The belt squat and sled were easy to assemble and the staff helped with loading it all into my vehicle. I will be buying more products from here in the future for sure 👍

Scott Comber 21/09/22

Bought some rubber mats and plates, prices were competitive and its nice to be able to rock up and just load into the back of your car.

Friendly staff.

These are good quality bumper plates for the price and cope well for CrossFit style WODs where weights are constantly dropped.
NC Fitness also have excellent customer service nothing is too hard for them.

Best investment in a long time I have a lot of knots in my shoulders and I suffer from sciatic pain as well this has helped me so much. My friends have used mine and have ended up purchasing the ball as well. Best investment in a long time.

Great quality stuff ordered skipping rope and a box jump and came quicker then expected. They also sent me some extra goodies which I was very happy with

Brett Nicholas 12/11/21

I've made 3 different purchases from NC Fitness, collecting one order in person, while shipping the other two orders. The quality of their products is fantastic, while their pricing is competitive. I have plenty of rogue fitness equipment too and the NC stuff is equal in build strength, quality and finish - though more affordable. I've brought dumb bells, plyo box, H-Series rig components etc. Their freight rates and shipping times are fair, given the weight of the products shipping. Keep up the great work team!

Aleksandra Gutowska 02/12/21

Amazing quality equipment and incredible customer service! I was on the hunt for a high quality belt squat machine and these guys delivered just that. Ordered and it was ready for pick-up a few days later. I ran into some hiccups with being able to pick it up, but the team at NC Fitness swooped to the rescue and delivered the parts free of charge. I could not recommend NC Fitness more! Thank you for helping me take my garage gym to the next level!!

Piga Charma 20/12/20

Really impressed with NC Fitness. Good Service and very reasonable prices. Products back in stock dates are genuine unlike other online retailers, who advertise false ETA and blame overseas shipping . I recently ordered some weight plates and a FID Bench. The quality is really good, exceeded my expectation.
Gym and Fitness (Force USA) on the other hand have doubled their prices to take advantage of this COVID Lock down.
Keep up the good work NC Fitness. Will highly recommend.

Lucy 11/10/21

Very efficient! I Ordered my weights on Tuesday arvo and received them Wednesday morning before 9. Thank you so much!

Samantha Beasly 12/09/21

I was after some dumbells as so many places were sold out and these guys offered such a big range at a great price! Plus they were despatched and delivered in under 2 x days! Absolutely great service and definitely will be ordering again! Thankyou guys!
