ProForm 505 CST Treadmill Review

The ProForm 505 CST Treadmill is a mid-range treadmill comparable to the Golds Gym 720. It has many of the same features of the 720 including adjustable incline, headphone jack for audio, a shock absorption system, and a robust digital display. Like the 720, the ProForm is well suited for heavy use and has a weight limit of 300 pounds.

  • Treadmill Weight: 191 pounds
  • Weight Limit: 300 pounds
  • Voltage: 110 V

Good for heavy running – The ProForm 505 is bulkier and heavier than many of the lighter budget treadmills, and has a weight limit of 300 pounds. This makes it well suited for more dedicated runners looking for a treadmill for daily use. ProForm stands behind the quality of their product, and the included motor has a 25 year warranty.

Shock absorption system – The ProShox cushioning system reduces wear and tear and the treadmill, and is helpful for those looking to reduce the impact using the treadmill will have on their joints.

Many features – The ProForm 505 Treadmill has many features including a quick adjustable incline up to 10 degrees, a large LED display with statistics reporting and pulse monitor, as well as 18 different workout applications.

Included headphone jack – A headphone jack makes listening to music on the ProForm 505 much more convenient. Just plug in your ipod to the headphone jack and your music will play out of the treadmill’s built in speakers.

High weight limit – Unlike budget treadmills with max weights of 200 – 250 pounds, the ProForm Treadmill has a max weight of 300.


Takes up some space – The ProForm is a full sized treadmill, and takes up much more space than some of the smaller budget models. Its high weight makes it difficult to transport, but like some of the smaller models it does fold up when not in use.

Lengthy assembling process – Assembling the ProForm 505 can be a long process, with many customers needing 2-3 hours to get it all put together. The assembly does go far easier with two people working on it.

Final Verdict

Comparable to the Gold’s Gym 720, the ProForm 505 is a solid mid-range treadmill at the $500 price point. It has many of the features found in gym-quality treadmills and is well suited for the daily runner. We give the ProForm 505 5/5 stars.
