For the Triphasic main exercises utilise compound exercises and use about 80 % of 1RM for movements with low quality repetitions such as 4 sets of 3 reps.. For eccentric focussed movement use a 5 - 6s tempo down
during the eccentric phase followed by an explosive concentric.
A standard tempo on a movement like a bench press might be as
follows: 2 -0-1, which is 2 seconds down
during the
eccentric phase when you're lowering the weight to your chest, no pause (when you change from
eccentric to concentric) and 1 second up when you lifting the bar upwards.
