The 200 lbs per stack may not be enough resistance for advanced lifters who require more weight, particularly for lower-body exercises like squats or deadlifts. - Assembly Time:
Assembling the DF2104 can be a time-consuming process, requiring multiple tools and some assistance. Plan to dedicate several hours to ensure it's set up correctly. - Cable Maintenance:
