As much as you can...make sure you beat that amount next time.
The weight lifted during a dumbbell curl should be challenging enough to perform 8-12 repetitions with proper form. Start with a weight that allows you to complete a set with good form, and gradually increase the weight as you become stronger. Aim for progressive overload to see improvements in muscle growth and strength.
The heaviest object that can be lifted would depend on various factors such as the strength and capabilities of the person or machinery doing the lifting. In general, the heaviest object that can be lifted by humans without specialized equipment is typically around a few hundred pounds. In industrial settings, cranes and other machinery can lift much heavier objects, ranging from several tons to hundreds of tons.
The potential energy of an object as it is being lifted comes from the work done against gravity to move the object to a higher position. This work done is converted into potential energy, stored in the object as its height increases.
A live load on your desk when doing homework could be the weight of your textbooks and supplies. A dead load on your desk could be the weight of the desk itself and any other furniture items on it.
Mechanical energy is used when picking up a package. The person exerts a force to lift the package, which requires energy input to do work against the force of gravity.

For Rock-Solid Core Strength - Dumbell RotationsThe dumbell is one of the most basic and versatile pieces of equipment in the gym, and with so many hundreds of ways to use the dumbell properly, it's surprising that so many people manage to find a way to use it incorrectly. Here are some basic dumbell exercises to get you started at the gym or at home.Basic Bicep CurlsOne of the simplest exercises in the world is the basic bicep curl, but many people do it improperly. For best results, keep your upper arm straight, never bend at the shoulder, and keep your elbow tucked into your side. Curl your wrist up and towards your shoulder when lifting, tensing every muscle in your arm, and let the weight back down gradually. Don't use your body to "heave" the dumbell up, use your arm only.Side LiftsHold a dumbell in either hand and raise your arms out to each side like a bird raising its wings. Do this gradually so that you can really feel the burn, and hold them out there for a moment. If you jerk them or swing them, you risk serious injury. Lower them gradually and repeat. You'll probably only be able to do a few reps at first, but soon you may be doing multiple sets of ten and up.Dumbell CrunchesA great way to work the abs is to simply hold a dumbell on your chest while doing crunches or sit-ups. The challenge here is doing a real crunch, a real sit-up, and not going halfway before flopping back down. The higher you hold the dumbell up on your chest, the more burn you're going to get. If you really want to get aggressive with it, some people will actually hold the dumbell over their forehead or above it for a serious burn.All of these workouts can be accomplished at the gym or at home with a couple of cheap dumbells. You can also hold dumbells while doing a variety of exercises like squats. If you're ever lost as to whether you're making a real impact on your body or not, just ask yourself: Can you feel the burn? If so, you're probably on the right track.
If you are eating healthy (veggies and fruits), and exercising often. If you are doing those things you should be losing weight.
The best source of exercising with dumbells is to set yourself at a specific weight hold dumbells either side of your hips and slowly move them up keeping arms locked out.. start doing at least 10 rest 2 minutes then another 10 continue doing so for 3 cycles then find another exercise to achieve.. that's my favourite source of exercise with a dumbell though
If you haven't lifted weights before a month of doing so can really improve your muscular appearance.
you start off with a low weight and then add weight a little at a time until u can only do a minimum of 5 reps, and always have some one to spot you for safety reasons.
There is no recognized standard but you're doing fine if you can bench your own body weight.
He lifted the boulder, but not without heavy exertion.you can not win without exertion . Your highest exertion is required.
No, not really. But it depends upon the exercise really, bench press you should usually be doing your body weight. Deadlift, probably twice your weight. Power clean around 150 - 200. If you are in great shape. And squat should be. About the weight of your deadlift minus about 100 pounds
Your upper body torso and hands/arms receive the weight when doing a handstand.
Negative training is a form of 'weight lifting' which focuses on the negative side of a rep. For example, if you were doing a bench press, when you raise the bar you then lower it back down very slowly, allowing your muscle fibres to tear from the strain of going against the pull of gravity. If you were doing bicep curls: you would focus on lowering the dumbell slowly back to the starting position after you have performed the curl. Negative training for some people gives better muscle building results as negative training with a spotter can include a greater amount of weight than if you were doing the normal reps and the muscle fibres are torn more, resulting in a bigger build during recovery.
You should go on eating, what ever you like. You must be knowing that you should not take the milk. That will increase your weight.
