Ultimate Upper and Ultimate Lower Body are compilation dvds complied from the Get Ripped II series circa 2001 and the Live series that came out the next couple of years. Along with the original advanced dvd (which is not part of this compilation), the classes Billy put out during this time are considered by Tae Bo aficionados to be his best and most difficult. Please note the production value is basically a class filmed on video and the since it is a compilation it can at times be choppy but you should be working and sweating so hard that these things should not matter.There are two primary workouts and two bonus add-ons. The bonus Ultimate Abs is five minutes of floor ab work. I think this one is the only real misstep on otherwise perfect dvd since it is little fast and too short for serious ab workout. Ultimate Butt is 5:10 of standing Butt that could be added to the Lower Body if you are glutton for punishment.Ultimate Upper Body - 52 minutes - this is a cardio class with focus on continuously moving arms the whole time. There is the standard 5 minutes warm-up and 2 minute stretches and then for next 33 minutes (38 if you count warm-up) you do cardio with punches, speed-bags and other arm combos. At the 44 minute mark you go down on floor for push-up series for two minutes and then 6 minute cool down.Ultimate Lower Body - 47:31 - You start with the first 9 minutes of Ripped Workout One and then for 42 minutes you kick, kick and kick some more with some horse squats and holds thrown in for good measure. This is all standing and it you are true Advanced you could throw on some ankle weights for truly killer leg workout. You cool down at the 42 minute mark and you will need it.Again great old school tae bo for fans of the Ripped Series or those newer to Tae Bo who want more advanced classes but are not bothered by old school production values.
