Is it better to have one-on-one executive training or to opt for a group setting? The answer is a clear, emphatic, definitive “It depends.” Sorry. But consider this: is a personal trainer the best option for losing weight? It would seem like it, wouldn’t it? But why are support groups, like Weight Watchers, so effective? You can see that there are benefits to both a personal coach and a group setting. It is the same with executive training.
