While weights are definitely not an absolute necessity, they can be very helpful in your arm fitness program. Simple resistance may not be enough for many women. This might be true for you if you have had a lot of exercise experience with your arms.

If you are more advanced in your arm work, bands might be only a temporary solution as you are getting back into your regular routine or if your pregnancy calls for cutting back on certain exercises.

There is not one weight that is right or wrong for everyone. The best test of weight limit is your comfort level. Lifting weights should be a slight strain, but it should never feel overpowering. Lifting too much weight can damage your muscles so watching what you lift is important. Increase your weights gradually. Consider a personal training meeting if you have significant questions about weights. Remember, it is not a competition.
