8 Week Triathlon Strength Training Program For Beginners. 

Triathlete with Wahoo Heart Rate Monitor

Triathletes are notorious for neglecting strength training. Strength training for triathletes requires a well rounded approach to address the demands of all three disciplines. In this 8 week triathlon strength training program for beginners, we will be using an Upper / Lower split.

U/L was picked to minimize the time in the gym and maximize strength gains. If the upper / lower split does not work for you, consider introducing a Push, Pull, Legs plan into your training routine.

If you’ve noticed below, there are no recommended weight ranges, since these are relative. The most important piece here is to use a weight level that will bring your muscles close to failure in the designated rep ranges.

Note: RIR stands for “Reps in Reserve.” RIR is the amount of reps you think it would take to get to failure from your last rep.

Week 1-2: Introduction Phase

Assisted Pull Up

In this phase, the goal is to introduce the muscles to strength training. We will be focusing on fundamental movements. The exercises chosen are compound movements that engage multiple muscles at once.

The body’s response to this phase is primarily neural. Your nervous system is learning how to fire the correct muscle fibers more efficiently, leading to initial strength gains without significant muscle growth.

Session #1: Upper Body

Goal: Focus on major muscles groups used in swimming (shoulders, chest, back) and overall body stabilization.

Session #2: Lower Body

Goal: Engage the key muscles used in cycling and running (quads, hamstrings, glutes, calves).

Week 3-4: Foundation Phase

Lat Pulldown

We introduce progressive overload in Week 3 to start building muscular strength. The intensity is increased. This will stimulate the body to increase muscle fiber recruitment and begin the process of muscle protein synthesis, leading to muscle growth.

Session #1: Upper Body

Goal: Introduction of weighted exercises to strengthen the arms, back, and chest. This will help improve strokes efficiency and biking stability.

Session #2: Lower Body

Goal: Build powerful leg muscles to improve cycling economy.

Week 5-6: Emphasis on Continued Hypertrophy

Pull Up

This phase is designed to push the muscles to work harder. The goal here is to generate muscular hypertrophy. This will result in greater power output and improved performance in each discipline.

Session #1: Upper Body

Goal: Increasing the complexity and intensity of workouts continues to strengthen the upper body, improving swimming and biking posture.

Session #2: Lower Body

Goal: The addition of more complex lower-body exercises helps increase power output during cycling and running.

Week 7-8: Advanced Phase

Weighted Pull Up

By week 8, you should have a solid base in strength training to continue your weight lifting journey. At this point you should be comfortable integrating complex compound lifts into your triathlon routine.

Session #1: Upper Body

Goal: Further develop strength, endurance, and power in the upper body.
