Huge difference here since lifting weights my glutes have lifted so much thanks to fitness blenders butt and thigh workouts. I never used dumbbells at first.. when I started using fitness blender I just used to do alot of cardio and no equipment workouts but now since using my power block weights (which is only 4 months) i see this huge difference I feel stronger better and more confident! It's a year today I've been working out with fitness blender and will be using fitness blender forever😀💪
