Don’t think I’ll go for the all out 4 weekly sessions,
Unless you do it ain’t Tabata training.
And the protocol is only properly tested on a stationary bike.
If you mess about with the protocol in ANY WAY WHATSOEVER you are ‘doing exercise’, not Tabata training.
Exercise science is the same as all other science – you do experiments, you get a result. With luck it’s repeatable. Then it’s a protocol.
You change any of the variables you have a new experiment, so it would be surprising if you got the same result. Of course you may get a better one, so good luck !
