Weight
For all dumbbell related movements, whether it is a unilateral (one side at a time) or bilateral (both sides at the same time) movement, we recommend entering the weight of a single dumbbell e.g. if using a 20 pound dumbbell for lateral raises, even though both arms may be moving together, a simple 20 is entered into the weight box.
Reps
When it comes to unilateral work, the recommendation is to start with the weaker side and work towards the target RIR/Reps given. Then, match that number of reps with the stronger side e.g. hitting 6 reps on a split squat on the weaker side would be matched by the stronger side, then a simple 6 is entered into the reps box.
