Chest Day at Planet Fitness: A Realistic and Effective Routine for Results

For many people starting their fitness journey, chest day is one of the most anticipated parts of the week—and for good reason. A strong, sculpted chest not only looks powerful but also improves upper-body strength and posture. But what if your gym is Planet Fitness, with its famously judgment-free zone and equipment that doesn’t include traditional barbells? The good news: You can still build an impressive chest with the tools available.

Here’s a breakdown of the best chest exercises at Planet Fitness, and how to structure a chest day that delivers real gains without needing a bench press.

1. Chest Press Machine (Seated or Incline)

This is the go-to alternative to a barbell bench press at Planet Fitness. It targets the pectoral muscles, shoulders, and triceps. To get the most out of it:

• Set the seat height so the handles align with mid-chest.

• Control the motion—don’t just slam the weights.

• Aim for 3–4 sets of 10–12 reps.

Pro tip: Use the incline chest press machine to shift emphasis to the upper chest for a more balanced physique.

2. Pec Deck (Chest Fly Machine)

The pec deck is underrated but powerful. It stretches the pecs through a full range of motion, emphasizing that deep contraction.

• Keep your back flat against the pad.

• Pause briefly at the peak of the movement.

• Don’t lock out your elbows.

Focus on 3 sets of 12–15 slow, controlled reps.

3. Cable Chest Fly (Low Pulley or Standing Cable Crossover)

Many Planet Fitness locations are equipped with cable stations, making this a must-do move on chest day.

• Stand with one foot forward for balance.

• Bring your hands together in a wide arc—like hugging a barrel.

• Adjust the cable height to hit different areas of your chest (high-to-low for lower pecs, straight across for mid-chest).

3–4 sets of 12 reps will leave your chest burning—in a good way.

4. Smith Machine Press (If Available)

Not every Planet Fitness has this, but if yours does, it’s a great way to mimic a bench press safely.

• Adjust the bench to flat or incline.

• Keep your shoulder blades retracted and core tight.

• Focus on a full range of motion and clean form.

This can serve as your “power move” of the day. Do 3–5 sets in the 6–10 rep range.

5. Pushups (Incline or Standard)

You can always rely on your bodyweight. Use a bench or step to make incline pushups easier, or perform standard ones on the floor to finish your chest day strong.

• Maintain a straight line from head to heels.

• Lower your chest close to the ground, then press up.

Pushups are perfect as a burnout finisher. Go for 2–3 sets to failure.

A Personal Note on Training at Planet Fitness

I used to think you couldn’t get a serious chest workout without barbells or heavy dumbbells. That changed a few years back when I started training at Planet Fitness during a move. I had to relearn how to focus on form, time under tension, and consistency. To my surprise, I not only maintained my chest strength—I actually improved the quality of my workouts. Machines and cables allowed me to isolate the muscles better, reduce joint strain, and stay consistent, even on busy days.

The key? Showing up and pushing yourself with what you’ve got. And Planet Fitness gives you more than enough tools to do exactly that.
