Heavy Lift

A lift is a weight transfer with a second mass involved, and it is the first exercise where the character has to convince the audience about something that is not part of their own body.

What the video covers

Using the basic character to grab an object and lift it. Constraints are introduced here, which is the technical spine of the exercise: how a hand takes hold of something, how the object then travels with the hand, and how that relationship is released. On top of that sit the principles the series has been accumulating: anticipation, follow through, overlapping action, easing, arcs, and secondary action. In-between work carries over directly from the hammer and the jump.

Why weight is the hard part

An object only weighs what the character says it weighs. The prop has no mass in the software. Everything the audience believes about it comes from what the body does: how long the preparation takes, which joints bend, how the spine leans, how much slower everything becomes once the weight is picked up.

Constraints are a technical tool serving a performance question. Attaching an object to a hand is straightforward. Deciding the exact frame the grip takes hold, and making the transition invisible, is the animation.

Secondary action is what sells the effort. A held breath, a shift of the supporting foot, a small correction of balance partway through the lift. These are not decoration; they are the evidence that the body is working.

What to watch for

• The moment of commitment. There should be a frame where the character has taken the weight and cannot casually put it down.
• Everything slows. A loaded body moves differently from an unloaded one, and the difference should be obvious.
• The constraint handover. Watch the frames either side of the grab for a pop.
• Balance shifts under load. The centre of gravity moves when the object is added, and the feet should answer.
