I find that most of Cathe's DVD's can be done with just hand weights. For toning i really like Muscle Endurance. It's an all weight total body workout that does high reps to build muscle endurance. Even though Cathe and crew use a barbell for some of the exercises you can sub in dumbells. I have done this many times. You also get Bootcamp on this DVD which is a great workout. You can sub in dumbells in that one too.
Not sure if you have a step, but I also like Cathe's circuit workouts like Low Impact Circuit which mixes step and weights. If you don't have a step then i would go for the Bootcamp/Muscle Endurance DVD. There are Leg Presses in Muscle Endurance but if you don't have a high step you could always do lunges or squats instead.
Kick, Punch & Crunch doesn't require any weights and you also get Legs & Glutes on this DVD.
You can pretty much sub in dumbells for the barbell in all her workouts.
Let us know what you decide on getting!
