Are You Ready For MAS Training?
Ok, full discretion… I’ve just nicked this video out of my Cardio Conditioning Program module, from my Minimum Equipment Program.
But I’ve been so busy filming, editing and putting the new program together in my brand new online coaching portal this last month, that I’ve not had time to prepare anything else!
It’s a great introductory video though! If you’ve not come across MAS training before (Maximal Aerobic Speed), then it’s something you NEED to get acquainted with.
I’ve used this interval training method with my face-to-face clients (and myself) for years, and I thought it’s about time I made it available online too.
The reason I love it so much, is it allows a precise personalised cardio training prescription. Just like I do with my strength and power training (using percentage of one-rep-max lifts).
If you’re fitter, it pushes you. If you’re lacking fitness, it comes in at the right level too. The key is that all training is based on percentages of YOUR maximum aerobic speed. So the volume and intensity I design into the training is delivered with accuracy.
Some food for thought!
