90kg multi gyms provide enough resistance for intermediate and advanced lifters. The weight stack offers approximately 18 plates at 5kg increments. Actual resistance at the handle depends on pulley ratios, often reducing effective weight by 30-50%.
These machines suit users who can bench press 60kg+ or lat pulldown 70kg+. Most 90kg systems feature heavy-duty frames rated for users up to 150kg. Better quality pulleys, thicker cables and reinforced stations handle the increased loads. Prices typically start around £900. Some manufacturers offer expansion kits to add extra plates.
