Looking for a recommendation for a 30 min stationary bike HIIT session. Currently I do 30 seconds ‘‘sprint’’ to 90 seconds ‘‘light’’, but which option would you recommend for resistance? I’ve tried both but I’m interested which you think would be best;
(a) ‘‘Sprint’’ level = 18, try and keep RPM above 100. For ‘‘Light’’, I drop the level down to 13 and stay around 80 RPM.
(b) Keep the level constant between the two, keep ‘‘light’’ RPM around 80 and just see how high I can keep it during ‘‘sprint’’ (i.e. 150 or so +).
The original article/routine I follow (from JB’s website) doesn’t specify either, but in other articles he seems to follow (b).
