I'm just starting strength training and wanted to get a pair of dumbbells. What is a good weight for a beginner? The ones I have been looking at come in either 2x 2.4lbs (1.1kg each) or 2x 4.9lbs (2.25kg each). Any thoughts?
If you are doing a range of exercises, you are going to need a range of weights. I'd suggest starting with an adjustable dumbbell (you can get a pair that goes up to 20lb each for about $50 at a sporting goods store). It'll be a lot cheaper than getting individual dumbbells.
And there are very few exercises that even a beginner would benefit from 2.5lb weights. If you can do more than 12 reps with a weight doing a compound exercise (uses more than one joint), it's too light. Most of us have purses heavier than 2.5 lb. And if you've ever picked up a load of laundry, you've deadlifted more than 2.5 lb.
ETA: And good for you for starting to do strength training - it's awesome! ;)
I am a beginner to strength training as well... and I cannot believe I have stayed away for so long. It's incredible.
I am starting with 10 lbs and I find that a perfect weight for me at this time. With certain exercises I have to use a much lower weight.
I bought 2 adjustable dumbells up to 20kg total, so if even it's 10kg each (so about 20lbs). Some exercises I can only do with 3 kg, some I can do with 10, some with 5. I'm very happy with them since one weight does not fit all exercises!
The side effects of allergy medications keep some people from using them. Natural remedies can be a great alternative, but some are more effective than others.
