For most people, here are the ranges of dumbbells that you might want to start with:
For a lighter set of dumbbells: 5 lbs, 8 lbs, or 10 lbs per dumbbell
For a heavier set of dumbbells: 10 lbs, 12 lbs, 15 lbs, or 20 lbs per dumbbell
We also recommend investing in a 1 light jumpstretch band, 1 medium jumpstretch band
If you are unsure of which weight to pick, sometimes it is beneficial to go to a gym and try picking it up and performing an exercise, such as a squat or overhead press to see how it feels.
If you are able to do 10 repetitions of an exercise and it feels easy, then the weight is too light. If you are only able to do 2 repetitions, then the weight is too heavy. By your third repetition, you should feel the target muscle engage. By your sixth repetition, you should start to feel tired.
It is okay if you don’t have the perfect weight for every exercise. You can sometimes adjust for this by doing fewer or more repetitions or moving at a slower pace.
