To give some background, I am an avid exercise enthusiast at an intermediate/advanced level. I usually buy most of my workouts from the US as there tends to be more variety, but of late, I have purchased some "home-grown" exercise workouts (all of Davina's stuff, Claire Richards, Mel B, to name a few).
There are 7 sections to this workout, including the warm up and cool down:
Warm up: fairly standard stuff here, with large range of motion movements and even some higher impact stuff such as skipping. Quick stretch for all the major muscle groups and then onto the:
Total Body Workout: Consists of fairly easy to follow aerobic movements, such as jumping jacks, skipping, a little bit of boxing, scissor jumps, etc. Jessie does all the high-impact stuff, and Paul (her trainer) shows low-impact modifications. There are also some push-ups (done at a very fast pace - more like pulse push-ups really) and a little leg work thrown in in the form of lunges.
Boxing: Various punching movements (jabs, crosses, upper cuts, hooks) combined into different short combinations. This section is upper body focused and doesn't include any kicks.
Lower Body: Standing leg work comes first, consisting of squats, lunges, and sumo squats (toes turned out to work the inner thighs), the latter being the most challenging as you hold the sumo squat in a pulses for a while. Then its onto the floor on all fours for some straight leg lifts, pulses, side knee lifts and side leg kicks done at a very fast pace - rinse and repeat on the other leg.
Arm work: only approximately 5-7 mins if I recall correctly? Very fast tempo, with the odd lower body movement thrown in making it more multi-joint. Both Paul and Jessie use water bottles - one of my biggest gripes as I think if you are going to exercise at least invest in a pair of handweights.
Abs: fairly challenging ab exercises, particularly as there is little to no rest between each different exercise. Standard crunches, reverse curls and plank work are some of the exercises here.
Cool-down: standard fayre of stretches for all the major muscles groups, although as I recall there are no specific lower back stretches.
I got a fairly decent workout and a good sweat going all out (aka following Jessie's higher impact versions) all the way through, and would rate this workout at an intermediate exercise level. As a reference, it was not as challenging as Davina's workouts.
I agree with the previous reviewer in that I found Jessie annoying at times - lost count of how many times she told us to "enjoy yahselves" and "suck in yer belly!". She seemed to be on a very intense endorphin high from her new exercise regime!
She does look amazing, and I guess I was hoping for a more intense offering from her - I'm sure she didn't get that great upper body definition from pumping water bottles for 5-7 minutes every other day! I also agree that her trainer Paul,did not have the most exciting of personalities, but then if he had been as "peppy" as Jessie, I probably would have switched off the workout and legged it to the chemist for some happy pills of my own!
