Introduction to F45 and HYROX
F45 and HYROX are two fitness movements that have taken the world by storm. F45 stands for Functional 45-Minute Training, a system designed to deliver full-body workouts that combine resistance, cardio, and hybrid training styles. HYROX, on the other hand, is known as the World Series of Fitness Racing, blending endurance running and functional workouts into one challenging competition.
So, how do these two come together? The answer lies in structured preparation — a 20-week F45 training plan tailored to HYROX events. This plan develops the perfect balance of endurance, power, and recovery for peak performance on race day.

Understanding the F45 Training Plan
Before diving into the 20-week structure, it’s important to understand the principles of the F45 training plan. The plan is built around short, high-intensity workouts lasting 45 minutes each. These sessions use functional movements such as pushing, pulling, squatting, lunging, and lifting — all of which directly translate to the demands of a HYROX competition.
The main idea is progressive overload — gradually increasing intensity over time. Each week targets a combination of cardio, resistance, and hybrid workouts to build endurance and muscular power simultaneously.
Why the F45 Training Plan Works for HYROX
HYROX events consist of 8 rounds of 1 km runs, each followed by a functional exercise such as sled pushes, burpee broad jumps, rowing, or wall balls. This requires not only strength and speed but also mental toughness and stamina.
The F45 training plan effectively mimics these conditions through diverse programming. The alternating cardio and strength classes train your body to switch between aerobic and anaerobic states — just like during a HYROX race. Moreover, the community-driven atmosphere of F45 studios keeps motivation high, which is crucial during a 20-week journey.
How to Prepare for HYROX Events
The 20-Week HYROX Journey
The 20-week program is divided into four main phases, each lasting 4–6 weeks. This gradual progression ensures your body adapts efficiently without overtraining. It blends F45 sessions with running workouts and HYROX-specific practice.
Let’s break down each phase of this comprehensive training cycle.
Phase 1: Foundation Building (Weeks 1–5)
The first phase focuses on creating a strong aerobic base and improving your overall movement quality. You’ll participate in 4–5 F45 sessions weekly, focusing on form, mobility, and light endurance.
Goals of this phase:
- Build cardiovascular endurance with easy runs (3–5 km).
- Master form for sled pushes, rows, and wall balls.
- Strengthen your core and stabilizers to prevent injuries.
Sample weekly structure:
- Monday: F45 Cardio
- Tuesday: F45 Resistance
- Wednesday: 3–5 km Run
- Thursday: F45 Hybrid
- Friday: Mobility / Stretch
- Saturday: Technique Practice + 4 km Run
- Sunday: Rest

Phase 2: Strength and Stamina Growth (Weeks 6–10)
In this stage, intensity ramps up. You start integrating interval running, heavy resistance training, and partial HYROX simulations. The body begins to adapt to the dual challenge of endurance and strength.
Key focus areas:
- Include 6–8 km interval runs twice weekly.
- Emphasize F45 “Athletica” and “Romans” sessions for power.
- Add partial HYROX simulations (4–5 stations per session).
Sample weekly structure:
- Monday: F45 Athletica
- Tuesday: 6 km Interval Run
- Wednesday: F45 Romans
- Thursday: F45 Redline
- Friday: HYROX Simulation
- Saturday: 8 km Steady Run
- Sunday: Rest

Phase 3: Peak Performance Phase (Weeks 11–16)
This phase simulates the real HYROX experience. You’ll combine running with all 8 functional movements in full or half simulations. The goal is to condition both the body and mind for competition day.
Focus points:
- Perform 2 HYROX simulations per week.
- Run longer distances (8–10 km) to build endurance.
- Maintain 3–4 F45 workouts focusing on heavy resistance and hybrid combinations.
Sample weekly structure:
- Monday: F45 Resistance (Heavy)
- Tuesday: Threshold Run (6 km)
- Wednesday: HYROX Full Simulation
- Thursday: F45 Hybrid
- Friday: Long Run (10 km)
- Saturday: Recovery Mobility
- Sunday: Rest
Phase 4: Taper and Recovery (Weeks 17–20)
As the race approaches, intensity decreases to allow recovery while maintaining sharpness. The final weeks fine-tune your pace, form, and mindset.
Objectives:
- Reduce volume by 40–50% while keeping movements crisp.
- Practice light simulations (4–6 stations).
- Focus on mobility, flexibility, and rest.
Sample weekly structure:
- Monday: F45 Light Cardio
- Tuesday: Short Run (3–4 km)
- Wednesday: F45 Hybrid (Low Intensity)
- Thursday: Mobility / Stretch
- Friday: Mini Simulation
- Saturday: Rest
- Sunday: Rest

Nutrition and Recovery Tips
Nutrition is just as vital as training. During your 20-week program, fuel your body with a balanced diet rich in protein, complex carbs, and healthy fats. Hydration plays a key role, especially during intense cardio and resistance days.
Pre-workout: Opt for oats, banana, or a protein smoothie.
Post-workout: Include lean proteins like chicken, fish, or tofu with whole grains.
Supplements: Consider creatine, electrolytes, and whey protein to support recovery.
Equally important is sleep — aim for 7–8 hours nightly. Use active recovery tools like foam rolling and stretching to stay flexible and reduce soreness.

How to Track Progress and Improve
Tracking progress keeps motivation alive. Monitor your weekly running pace, sled weight, and reps in major exercises like wall balls or burpees. Many F45 studios use performance tracking apps that help visualize progress over time.
Set small milestones:
- Week 5: Run 5 km without stopping.
- Week 10: Complete 4-station HYROX simulation.
- Week 16: Full simulation under target time.
- Week 20: Race day performance.
Consistency is the real secret weapon of this plan.
