So imagine someone is doing [this lifting exercise](https://hips.hearstapps.com/hmg-prod.s3.amazonaws.com/images/workouts/2016/03/dumbbellbulgariangobletsplitsquat-1457046602.gif). However instead of the dumbbell being held at his chest, the lifter uses his arms to keep the height of the dumbbell static to the ground. So at the bottom of the rep the dumbbell would maybe be a little above his head and at the top of the rep the dumbbell would be back at his chest.

My question is if you performed the exercise with the weight's height remaining static would your leg still be using the same amount of force to get to the top of the rep compared to the lift being performed with the weight moving with the lifter like the gif above.
