Cathe Live PHA Plus Cardio Blasts

Cathe Live Review: PHA Plus Cardio Blasts

PHA Plus Cardio Blasts is a cardio and strength circuit workout from Cathe Live. I absolutely loved this workout. After my discovery of Leg Day (Click HERE to see the Review) as my perfect Lower Body workout, this is definitely my perfect PHA workout! It has the same excellent strength training approach – alternating lower and upper body exercises with only short rests in between - plus Cathe added in actual cardio blasts and best of all there is absolutely NO repetition! That is always my only complaint, with Cathe’s PHA workouts, that you usually do a giant set of 6-8 exercises, alternating lower and upper body, and then repeat them two or three times and I am just not a fan of lots of repetition. Cathe’s new LITE series included PHA 2 and I really enjoyed that workout as she only repeats the exercises twice – but this was even better. (To see my review of LITE PHA 2 – click HERE). Also Cathe has 3 other live PHA workouts and two DVDs – all of which are pure strength workouts.

PHA, in case you aren’t familiar with the term, stands for Peripheral Heart Action Training and as Cathe states “the goal is to maximise blood flow between the upper and lower body, while shortened rest periods keep your heart rate up for cardiovascular and fat-burning benefits”. This workout definitely achieves that.

PHA Plus Cardio Blasts involves a number circuits, each consisting of a cardio blast, a lower body and an upper body move. Once completed, you then move on to the next circuit – so there is lots of variety and it moves quickly so you have no chance to get bored. I loved the flow of this workout and the rep patterns are varied to keep you engaged throughout. The weights used are fairly light but you could easily increase them, as the pace is reasonable and it is not too high rep. You could also raise the step height, as well, if you want to really challenge yourself.

All of the cardio blasts are just straightforward Cathe style intervals – no choreography and they are all done on the floor. Those that use the step only have your hands on the step so you are not actually jumping on or off the step at all. The cardio blasts were a nice way to get my heart rate up a little higher and they were all nice straight forward moves so no dread factor. Even the one arm burpees were fine as you have your hands on the step.

The strength exercises are all fairly traditional moves and as the weights were lighter (I matched Cathe’s weights for most exercises, just increasing on squats and deadlifts) this felt slightly more of a metabolic workout than a true strength workout. You do hit each muscle group and I did feel the work but you would probably need to go a bit heavier to feel it in the same way I do for her pure strength versions of the PHA workouts – particularly the Strong & Sweaty DVD.

My only tiny gripe is that the cool down stretch seemed a little short, I didn’t feel like I stretched out my upper body, as well as I would have liked, so I just added a few extra stretches on at the end. Overall, though this is a real winner and one I will definitely be returning to frequently.
