Strong Legs for Stronger Performance: A Triathlete’s Guide to Leg Day

Endurance athletes often hear, “You bike and run, so do you really need to train your legs?” The answer is a resounding yes! While cycling and running certainly challenge your lower body, strength training is essential for building durability, power, and balance—all of which help you go faster, longer, and avoid injury.

As a huge advocate of strength training (I even self-published a book on it!), I can’t stress enough the benefits of hitting the gym, especially during the off-season. But even during peak training, incorporating strength sessions into your routine can elevate your performance.

Ready to start? Here are Six Leg Day Exercises that are perfect for triathletes. These can be done at the gym or home, with minimal equipment.

Jumping Squats

This explosive move builds power and endurance by targeting your quads, hamstrings, and glutes.

  • How to do it: Squat down, then jump as high as you can. Land softly and repeat.
  • Pro Tip: Keep your core tight and chest lifted to maintain good form.

 

Box Jumps

Box jumps add height and intensity to your workout, strengthening your quads, hamstrings, calves, and hips.

  • How to do it: Jump onto a sturdy box or step, landing softly. Step or jump back down and repeat.
  • Pro Tip: Start with a lower height and work your way up to prevent injury.

Jumping Lunges

An advanced lunge variation that builds strength and coordination.

  • How to do it: Begin in a lunge position. Jump, switch legs in mid-air, and land in the opposite lunge.
  • Pro Tip: Focus on control and avoid letting your knees slam into the ground.

Lunge Walking

A simple yet effective way to build strength and stability.

  • How to do it: Step forward into a deep lunge, then bring your back leg forward into the next lunge. Repeat as you “walk” across the room.
  • Pro Tip: Hold dumbbells for an added challenge.

Single-Leg Squat (Pistols)

A challenging move that improves balance and unilateral strength.

  • How to do it: Stand on one leg and lower yourself into a squat while keeping the other leg extended straight in front of you.
  • Pro Tip: Start by holding onto a wall or chair for support if needed.

Side Squat

A hybrid of a squat and lunge that targets your inner thighs and glutes.

  • How to do it: Step out to the side into a squat position, then return to the center. Repeat on the other side.
  • Pro Tip: Keep your chest lifted and weight in your heels.

Important Reminder for Triathletes

Leg day doesn’t mean trashing your legs with every exercise on this list! Incorporate 2-3 moves into your routine, depending on your training volume and race schedule. Remember, strength training is meant to complement your endurance work, not leave you too sore to bike or run.
