Hi Barb,
Based on what you've told me, here's what I would suggest.
1) Muscle Endurance/BootCamp DVD- Muscle Endurance is a total body weight workout. It has terrific music and is very comprehensive. Equipment used includes various dumbbells, a barbell (dumbbells or your body bars would work as substitutes), a high step (your FL will work just fine), and a med ball. Bootcamp is a circuit workout where you do 8 cycles of cardio, lower body weights, upper body weights, and abs. The cardio is very basic so no need to worry about choreography. Equipment used includes a high step (once again, your FL is fine), various dumbbells, a barbell, and a med ball. Both of these are super workouts and a lot of fun.
2)Pure Strength DVD or Pyramid Upper/Lower Body DVD- Pure Strength is the best 3 day split DVD, IMO. Since this is an older title there aren't any cool premixes to play with which is a bummer. Equipment used is a step bench used as a weight bench, dumbbells, and a barbell. The leg workout uses a body bar for the floor work and a high step (or FL). The Pyramids are a great two day split and you have premix options to pyramid up or down only, and there is a special bonus premix combining the two for a total body workout in about an hour. The upper body workout uses the step as a bench, dumbells, and a stability ball for the ab work. The lower body tape uses a barbell, a high step (or FL) and a stability ball for the floor work. Really, it's a matter of preference.
3) Cardio options- One option would be to try a kickboxing workout, which I would recommend Kick Punch Crunch (Legs and Glutes is the other workout on the DVD). This one is pretty basic choreography and you don't have to be a kickboxing guru in order to have fun. This workout uses a stability ball for the ab work. If you would consider step, the I would suggest Cathe's Classics DVD. This has 3 of her older step workouts on it and these are not as choreographically advanced and are taught at a slower speed than her newer stuff. IMAX 2 (has Cardio and Weights as the other workout on the DVD. This workout has some choreography in the step sections that may take a few times to get down. A lot of Cathe's step workouts feature moves that were introduced in previous workouts, hence the Classic rec. above) is an awesome step workout. The blasts are not tough at all in choreography. The mini step routines are short and repeated 6 times before the blast so you probably would do okay. Be warned, this is one kick butt workout. Both of these workouts are best done with a full size Club Step.
I would not recommend either of the High Step workouts unless you are willing to purchase a high step. The FL will simply not hold up to the cardio in these workouts.
HTH,
