Briefly

"Rather than directly bracing the back and giving up on proper lifting form," U-M professor Robert Gregg notes, "we strengthen the legs to maintain it." This innovative approach with the knee exoskeletons allows for enhanced lifting capabilities while preserving good ergonomics during manual tasks.
Test subjects were required to move a 30-pound kettlebell up and down a flight of stairs. Researchers note that the tech helped them maintain good lifting form, while lifting more quickly. This showcases the effectiveness of the knee exoskeleton in real-world applications.
