I read this article and it said that the only problem to lifting heavy weights late in the pregnancy was because of the womans center of balance being thrown off and she could hurt herself. But lifting weights over twenty pounds did not effect the baby's growth or cause defects.

I think its ten pounds and under it could be twenty so be safe and stick to ten
I have a very physically demanding job and I am in my first trimester. Can I remain as physically active as I was when I was not pregnant. If so, at what time should I not be lifting as much. I am lifting anywhere from 20 to 30 pounds.
The maximum load that the crane can lift is 18 metric tons (39,690 pounds), but the crane cannot lift that much weight if the load is positioned at the end of the jib. The closer the load is positioned to the mast (center of rotation), the more weight the crane can lift safely.
From today.msnbc.msn.com: "Late in pregnancy a woman's ability to safely lift a load decreases, mostly because her center of gravity and balance have changed and additionally because the hormones of pregnancy have caused her connective tissue, ligaments and tendons to soften. So if she lifts a heavy load she can injure herself, but will probably do no harm to the pregnancy or the baby. There are no studies that show that lifting more than 25 pounds has an effect on birth weight or prematurity. The current recommendation is that the maximum load a pregnant woman should lift in late pregnancy should be reduced by 20 to 25 percent from that which she was able to lift in her pre-pregnancy state."
You should not lift heavy things when you are pregnant.
Yes, in order for a plane to land safely, the lift (created by the wings) must be greater than the weight of the aircraft. This helps the plane maintain control during the descent and landing process.

To safely lift a barbell with weights attached and maximize strength training results, focus on proper form and technique. Start with a weight that is challenging but manageable, and gradually increase the weight as you get stronger. Engage your core, keep your back straight, and lift with your legs rather than your back. Use a spotter if needed, and listen to your body to avoid injury.
To calculate whether the lift can handle a specific load, you need to know the weight of the load and the load center. If the total weight of the load is less than or equal to 6000 lbs and the load center is 24 inches or less, then the lift should be able to handle it. If the total weight exceeds 6000 lbs or the load center is greater than 24 inches, the lift may not be able to lift the load safely.
To safely lift and support a baby's weight when pulling them up by their arms, it is important to always support their head and neck with one hand while using the other hand to hold their underarms or torso. This helps prevent any strain on their arms and shoulders. It is also recommended to lift them slowly and gently to avoid any sudden movements that could cause discomfort or injury.

To safely lift someone without causing injury, use proper lifting techniques such as bending your knees, keeping your back straight, and using your leg muscles to lift. Make sure to communicate with the person being lifted to coordinate movements and avoid sudden jerks. Additionally, consider the person's weight and your own physical capabilities before attempting to lift them.
It would be extremely unusual for a 70 year old woman to be able to lift that much weight (indeed, most women cannot lift and carry a man even when they are in their prime of youth), but it is not impossible for someone who has gone to great lengths to exercise and maintain physical strength.
The weight that a mouse can lift will depend on its size. It is estimated that mice can lift things that twice their body weight.
