1. When you say lose weight, you mean lose fat (nobody should want to lose weight). You should do aerobic exercise.

2. The fitness you said should be the increase of strength. This is muscle building. You should do anaerobic exercise.

Dumbbells with small weight and many times can be considered aerobic, for example, a 5kg dumbbell can be lifted 50 times.

Dumbbells are heavy and few times, which is anaerobic exercise. If the general weight is 8, choose the weight within 8.

It is recommended to run and jump rope if you want to lose weight, and the effect will be better with anaerobic exercise.
