For drop sets, the weights should be medium to heavy.
For example, you come and do 10 reps with a weight of 20 kg
You cannot repeat immediately after finishing 10 reps!
So you have to reduce the bar on the dambel. Lose some weight. For example, it can be 18 kg
Try 10 repetitions again
After 10 repetitions, you probably won't be able to move any further.
The bar should be reduced again, like 16 kilos. Try again for 10 repetitions
The number of sets should be about 3 sets. Repeat between 12 and 8
