Hi Connor. An excellent way may be to approach some of your local gyms and ask them. Gyms are constantly upgrading their equipment and oftentimes are willing to donate their used equipment for a good cause or use. You may need to run this idea (you should) by your school’s administration to get their official endorsement and to see if such a donation might even qualify for a tax-deduction for the donating gym.
Of course, ANY donated or otherwise used equipment should be thoroughly checked-out by a qualified fitness equipment technician before you use it to make sure that it’s safe!
I hope that this helps.
