Hey @bvanbieze, a big welcome
Yeah, so this isn’t a new thing-the app will always tell you if you need to use a pair of dumbbells.
One thing to say is that we always encourage you to adapt the exercise assigned in such a way that will allow you to complete it.
Firstly, let me explain part of the thinking, dumbbells can be very expensive and many users simply won’t buy lots of different pairs of dumbbells-and, to be honest, it also isn’t hugely necessary if you are able to adapt the exercise anyway. If we made it absolutely required to use a pair, the cost in itself would be hugely prohibitive for many, and you would be excluded from a huge range of exercises once your weight got past a certain point (in your case 2x8kg). We try to design our Training Journeys to be accessible for as many people as possible.
For example, Dumbbell Bench Presses…you would essentially be excluded from this great exercise if a pair of dumbbells was absolutely required. 8kg is much lighter than the weight you are being assigned.
Where this happens, all you have to do for the vast majority of exercises is use the single dumbbell assigned, complete the reps on one side, then switch over and complete the reps on the other side.
This isn’t the highest weight you have available though, you should simply use your 11kg dumbbell here.
Now…I grant that adapting the exercise in this case isn’t immediately straightforward (Dumbbell Squats), and for most Athletes probably means replacing the exercise with Goblet Squats, but it’s not the only way to do so, you can still complete this exercise with very good technique using a single dumbbell.
