The Back Extension Exercise
Being one of the most common and effective gym exercises for lower back strength, the back extension also activates the hamstrings and glutes.
Your mid and lower back muscles stabilize your posture and assist you in lifting bulky load while preventing spinal injury. As lower backache is an extremely common issue worldwide, training your back muscles for strength is essential. The back extension exercise works just these muscles that work to protect your spine. These benefits also make the effective components of programs meant to relieve lower back pain.
The two varieties of back extension stand are flat, and inclined at 45 degrees. Although each one fulfills the purpose of the exercise and can be used along with or after the other, the inclined bench is recommended since it exercises your target muscles via a wider range of motion than the flat bench exercise.
Back extensions without any weight are usually done with more reps, around 15 to 20 or higher. The exercise can still be done by adding weight and lowering the number of reps to a range like 8 to 12 for each set.
Quick Judgement Tips
#Originality:
1. Check whether there is an R&D center to design its own strength equipment; talk with the designers about design concepts.
#Movement Angle:
2. Ask designers at the R&D center if they usually work out with gym equipment. Designers who do not work out with gym equipment should never design any strength training machine.
3. You should try the fitness equipment yourself. You need to experience the following three aspects:
- Whether it is smooth to use.
- Whether specific equipment is activating your targeted muscle group.
- For converging and diverging equipment, whether there is a peak contraction experience.
#Finish:
4. Know about the specific treatment methods applied to the surface.
5. Check if the surface is smooth to the touch.
6. Take a hard metal object, such as a key, and scratch the surface of the equipment in order to see the adhesion of the surface coating.
#Frame Pipe:
7. Pipe standard: ask the supplier about the standard of this pipe. In China, for example, you should expect fitness equipment pipes to meet Q235 standard.
8. Pipe Size: Look for 40mm x 80mm and above for the length and width of the frame pipe, preferably with 3.0mm in thickness.
9. Treatment: bending production procedure is preferred over cutting and welding.
10. Check the thickness of the raw material, not the the painted tube.
#Connections:
11. Ask the factory representative about the treatment methods, as well as the theoretical basis of the connection.
12. Check the thickness of the connecting plate and the strength of the screw.
#Seat
-Seat Fillings:
13. Press the seat firmly with your thumb or apply a specific instrument to measure its density level.
-Seat Leather:
14. Smell: Check whether there is any pungent smell.
15. Tactile impression: Touch the surface by hand and confirm the tactile impression.
16. Density: Observe from the cut/side surface and check its stomata; the more stomata there is, the lower the density and quality.
17. Thickness: Check the thickness of the material; the thicker, the better;
-Seat Support Plate

-Cable:
26. Check the thickness of the cable; the thicker it is, the more solid the cable will be.
27. If you buy for commercial use, never be cheated by manufacturers who apply home use material to industrial equipment.
28. Ask about the maximum load capacity along with fatigue test report and check the results.
#Safety:
29. Meet the standard ISO20957: Check whether there is a certificate of ISO20957, which means the equipment has passed the International Organization for Standardization.
30. Stability: Try to push a pin-loaded machine to check if it is stable. On machines like the Lat Pulldown, select the maximum weight, then suddenly loosen the handle to see if the device is still stable.
31. Total net weight: subtract the weight plates; the heavier, the safer.
32. Overall structure: the surface of the fitness equipment pipe should be free of any protrusions so as to avoid injury.
33. The edges and corners of the surface should have a radius r ≥ 2.5mm. They should also be free of burrs and make use of round corners.
34. tube ends: All the tube ends should be in the accessible hand, and the foot area should be closed off.
