Who Is Tom Platz?

Tom Platz, hailing from Fort Sill, Oklahoma, isn’t just a name in bodybuilding; he’s a legend. Platz carved his path to fame during the dynamic era of the late 1970s and 1980s old-school bodybuilding scene. What sets him apart? Well, his massive, awe-inspiring quadriceps that became the stuff of bodybuilding folklore. While he never clinched the coveted Mr. Olympia title, Platz secured a third-place finish in the 1981 Mr. Olympia, accompanied by six top 10 finishes.

In addition to his achievements in the Mr. Olympia competitions, Tom Platz tasted success in the prestigious Mr. Universe events, securing a notable third-place finish in 1978 and attaining the coveted first-place title in 1980. These victories not only highlighted Tom Platz’s versatility but also emphasized the defining features of his career in the fiercely competitive realm of the golden era of bodybuilding, competing against the likes of Arnold Schwarzenegger and Frank Zane. He also once performed a 500-pound back squat for 23 reps.

His unwavering dedication to leg day and a distinctive and renowned training style in his bodybuilding workouts emphasized Platz’s unique approach to sculpting a legendary physique.

If you aren’t up for the grueling challenge that is Tom Platz’s leg workout, don’t fret—I’ve locked down some easy modifications for you later on. Also, I’d highly suggest you warm-up first before engaging in training of this volume.

Exercise	Sets	Reps
Back Squat	8-12	5-20
Hack Squat	5	10-15
Leg Extensions	5-8	10-15
Lying Hamstring Leg Curls	6-10	10-15
Standing Calf Raise	3-4	10-15
Seated Calf Raise	3-4	10-15

Now that you’ve explored this leg-pumping workout, let’s break down the exercises and dive into the rationale behind each movement.

Back Squat

Why do it: The back squat may not isolate muscles like leg extensions or hamstring curls, but they offer a distinct advantage in overall strength and engagement. This compound exercise allows for heavier loads, developing your quadriceps, hamstrings, and glutes, and engaging the core and stabilizing muscles.

Adjusting foot placement or stance can target specific muscle groups, like the quadriceps. The versatility of back squats makes them fundamental for building strength and muscle mass in the lower body.

How to do it:

Load your weight, then position your hands on a racked barbell just outside shoulder width.
Step under the bar, squeeze your traps, and rest the barbell on your upper back.
Step back from the squat rack, standing firmly with your feet hip-width apart.
Brace your core, bend your knees, and descend into a squat (aim for 90 degrees).
Drive through your feet to stand back up.
Repeat for desired reps then rerack the barbell between sets.

Expert tip: Perform your sets of squats with a controlled tempo for the best muscle engagement.

Hack Squat (Machine)

Why do it: Utilizing the hack squat machine doesn’t require your upper body to stabilize a barbell as needed with back squats. Why does this matter? You can move heavier weights for more volume. Like back squats, you can position your feet closer to target your quadriceps or widen your feet to focus on your glutes and adductors.

This combination allows for more muscle-building reps while enhancing your strength. A leg press is an effective substitute if your gym doesn’t have a hack squat machine. You can also perform a hack squat using a barbell.

How to do it:

Select your preferred weight, then position yourself inside the machine with your back against the pad.
Place your feet hip-width apart on the platform.
Hold the handles or sides of the machine for stability.
Bend your knees and lower your body, keeping your chest up and back flat. Aim to lower until your thighs are parallel to the ground.
Push through your feet to lift the platform and return.
Repeat for desired sets and reps

Expert tip: Knock out a set or two of hack squats without pausing between reps (unbroken reps) to fatigue your muscles.

Leg Extension

Why do it: Leg extensions allow you to target your quads directly, developing chiseled legs and giving the vastus medialis that teardrop appearance. Compound exercises are great for building strength and muscle mass, but they don’t allow you to isolate muscle groups for focused reps. This is why leg extensions are an excellent supplement to squeeze out extra quad-focused reps in any muscle-building program. That said, if you do wish to isolate this movement, you can do so by working one leg at a time.

How to do it:

Select your preferred weight and sit against the machine, aligning the pad with your ankles.
Straighten your legs, lifting the padded lever by engaging your quads.
Squeeze your quadriceps at the top without locking your knees.
Lower in a controlled manner to the starting position.
Complete the desired sets and reps.

Lying Leg Curls

Why do it: Hamstring curls might not boost your strength like an RDL workout or deadlift variations, but leg curls are effective for developing muscle mass by isolating the muscle group, particularly the sartorius. A study published in April 2021 in Medicine and Science in Sports and Exercise¹ highlighted that the lying hamstring curl resulted in more significant growth of the sartorius muscle compared to its seated counterpart.

Foot positioning also plays a pivotal role in hamstring development, with a wider placement focusing on the lateral hamstrings and a closer position targeting the medial (inside) hamstrings.

How to do it:

Select your preferred weight and lie face down on the leg curl machine.
Position your ankles under the pad.
Curl your legs upward, bringing your heels towards your glutes.
Squeeze your hamstrings at the top.
Lower the roller pad down with control.
Repeat for desired sets and reps.

Standing Calf Raise

Why do it: Calf exercises play a crucial role in lower leg development; selecting the appropriate variation aligning with your goals is essential. The standing calf raise builds muscle mass in the gastrocnemius, the prominent and visible calf muscle. This variation enables a full range of motion, delivering an enhanced stretch and contraction stimulus to the lower legs for calf development.

Experiment with two-leg and single-leg variations, tempos, and pauses at peak contraction to vary the training stimulus.

How to do it:

Stand with your feet hip-width apart.
Place the balls of your feet on the edge of a step or platform.
Rise onto your tiptoes, squeezing your calf muscles.
Gradually lower your heels below the step, feeling a stretch.
Repeat for desired sets and reps.

Seated Calf Raise

Why do it: The seated calf raise explicitly targets the soleus’s development, the deeper muscle of the calf in your lower leg. Due to being positioned in a seated stance, this variation deliberately minimizes the involvement of the gastrocnemius, emphasizing activation and engagement of the soleus muscle. Focus on a strong contraction at the top of each rep and a slow lowering to really drive gains in size and strength.

Integrating standing and seated variations into your lower-body workouts is critical to achieving a well-rounded and comprehensive development of your lower legs. Additionally, if you don’t have access to a calf raise machine, you can still do this exercise with a barbell across quads.

How to do it:

Select your preferred weight and sit on a calf raise machine with your feet positioned on the platform.
Push through the balls of your feet, lifting your heels.
Squeeze your calf muscles at the top.
Lower your heels below the platform for a stretch.
Repeat for desired sets and reps.

Tom Platz Leg Workout Benefits

Exercise Sequence

Tom Platz’s leg workouts were ordered in an optimal sequence, focusing on multi-joint compound exercises first, then exhausting the muscles with high-volume single-joint exercises. Starting your workouts with compound lifts first allows for greater increases in strength. A December 2017 study in Frontiers of Physiology² showed that multi-joint exercises are best for increasing measures of strength and recruiting a more significant number of muscle fibers via neural adaptations. This allows for greater muscle activation during compound lifts and carries over into your following single-joint, isolated exercises.

In addition to enhancing strength and muscle recruitment, knocking out sets and reps of strength exercises followed by isolated movements increases your ability to exhaust your muscle groups, which can lead to improvements in muscular size³ and endurance⁴.

Variable Reps—Strength, Size, and Endurance

You’ll rarely find a training program with loading recommendations⁵ that target the three principal muscular adaptations of resistance training. In this workout plan, you’ll work through strength-focused rep and hypertrophy-inducing rep ranges and finish the workouts with high-volume training that targets muscular endurance. This concept keeps every workout challenging and helps you avoid stagnant sessions, increasing creativity and fun!

By incorporating variable reps into a training program, you can optimize your workouts for a well-rounded approach, targeting different energy systems and physiological adaptations.

Targets All of Your Leg Muscles

Tom Platz’s leg workout is like an all-inclusive stay for leg training—in one gym session, you’ll target multiple muscles⁶ in your lower body, bolstering strength, size, and endurance.

Back squats start your sessions and are the lead compound lift for a reason, targeting your quads, glutes, hamstrings, calves, and adductors with each rep. Shifting to hack squats will reap the same benefits of a back squat but allow you to train with more volume and potentially more weight.

How to Modify the Tom Platz Leg Workout

After looking closer at the Tom Platz leg workout, you wouldn’t be wrong in thinking it’s a little extra. Tom Platz was training for competition, after all. Here’s how you can take the principles of the leg workout above and adapt them to suit your training needs.

Beginner to intermediate-Friendly

Jumping right into Tom Platz’s leg workout might not be the best choice for most gym-goers, especially beginners and those in the intermediate stage. Constructing a beginner workout plan inspired by Platz’s leg day involves a careful and safe progression. Starting gradually is vital, and my top recommendation is trimming the volume.

By incorporating correct progressions and a dose of balanced volume, you’ll be heading toward an effective and sustainable leg training routine. Check out the modifications below. I dropped the volume considerably and gave you better exercise options to boost your base strength.

This beginner workout will build the foundation of movement and strength. These exercises will allow you to progress movements from the beginner to the intermediate workout. The volume is lower, allowing you to increase intensity (weight lifted) weekly and focus on good form.
