One Set To Momentary Muscular Failure (MMF) | HITuni

Sean performs a set of the Chest Press to Momentary Muscular Failure (MMF). Note how Sean's performance of each repetition actually improves in the middle and latter parts of the set, compared to the first couple of repetitions.

At 1:50 (on the YouTube timer) Sean commences a repetition that is exceptionally challenging to get out of the lower turnaround, and yet with a high level of focus and effort he is able to do so.

At 2:00-2:01 Sean is unable to quite lock out his elbow joints, and the eccentric starts a little out of control, MMF may have already occurred in the triceps at this point.

At 2:06 into the set Sean attempts one more positive repetition, which he is unable to get out of the lower turnaround- the set culminates in MMF.

90-120 seconds are ideal to exhaust all X2 fibers. This set was to long - it means to low intense on muscle.

120 seconds Time Under Tension is about 3 sets worth of working sets. The difference is that if you did three sets, you would complete each rep with a higher percentage of 1RM whereas to maintain a two minute TUT like this video your intensity has to drop. As we know, volume and intensity are the primary roots of hypertrophy. Intensity being relative load, not maxing out on reps. Otherwise pushups would make everybody bodybuilders. I've done this myself in the past and tried maxing out a single set. It does not work effectively.

It however may be a great way to maintain fitness or strength when you don't have time to work out. But you can always make time to workout.
