The answer to this question depends on many variables:
-Fitness level of the participant
-Length of the triathlon event (sprint vs. ironman)
-Areas that need improvement (aerobic, anaerobic, swimming, running, biking, all of the above, etc.)
-Time left to the event
-Indoor or outdoor training (I prefer outdoors)
The strength training program for a triathlon event it varies depending to the individual, so without much information here it’s difficult to give you a better answer. Some general information will not be much help in answering this question.
Is strength training necessary?! Well not if you don’t want to be able to fully enjoy any activity.
And the program that I would suggest is one that has been based on foundation mobility, stability, and strength (which is always as balanced as possible). Then progress to help the client reach their goals without losing or compromising mobility, stability and strength.
For fitness professionals to be capable of addressing this type of client centered service should be the goal of all fitness professionals.
