    To summarize: driving your hips briefly increases the back angle θ by Δθ, which increases the moment τ by Δτ. If Δτ is large, even if τ is also large, your back is still strong enough to support τ + Δτ. But you can't react quickly enough to prevent instability/flexion. The solution is to start with large θ and τ (bend over), which makes Δτ small (per Figure 4).

    That's an awfully short article.
