Thursday: Exercise Basics – Form and Safety

1. Mastering Proper Form for Foundational Exercises

Proper form and exercise safety maximize results and prevent injuries.

Today’s lesson will cover:

1️⃣ Foundational exercises & proper form 🏋️‍♂️

2️⃣ Warm-ups, cool-downs & stretching for injury prevention 🔥

3️⃣ Using RPE (Rate of Perceived Exertion) to regulate intensity ⚖️

Good form ensures muscle activation, efficiency, and injury prevention. Here’s how to execute key exercises properly:


🏋️ Squat (Legs, Glutes, Core)

✔️ Feet shoulder-width apart, toes slightly out.

✔️ Keep chest up, engage your core.

✔️ Lower until thighs are parallel to the floor (or deeper if mobility allows).

✔️ Knees should track over toes, not cave in.

✔️ Drive up through heels, not your toes.

🔴 Common Mistakes:

❌ Knees caving in

❌ Rounding the back

❌ Lifting heels off the ground


💪 Push-Up (Chest, Shoulders, Triceps, Core)

✔️ Hands slightly wider than shoulder-width.

✔️ Body in a straight line from head to heels.

✔️ Lower until chest nearly touches the floor.

✔️ Elbows at 45-degree angle to the body.

✔️ Push back up without flaring elbows.

🔴 Common Mistakes:

❌ Sagging hips or arched lower back

❌ Not going low enough

❌ Flaring elbows too wide


🏋️ Deadlift (Glutes, Hamstrings, Back, Core)

✔️ Feet hip-width apart, barbell close to shins.

✔️ Grip the bar just outside legs, neutral spine (no rounding).

✔️ Hinge at the hips, then drive through heels to stand up.

✔️ Lock out with hips & glutes, not the lower back.

✔️ Lower the bar with control, keeping it close to the body.

🔴 Common Mistakes:

❌ Rounding the lower back

❌ Using only the lower back instead of hips & legs

❌ Shrugging shoulders at the top


2. The Importance of Warm-Ups, Cool-Downs & Stretching

🟢 Warm-Up (5–10 Minutes Before Every Workout)

A proper warm-up prepares muscles, increases blood flow & prevents injuries.Example Warm-Up Routine:

✔️ Light Cardio (2–5 min): Jump rope, jogging, or cycling.

✔️ Dynamic Stretching (2–5 min):

  • Leg swings (for hips & hamstrings)
  • Arm circles (for shoulders)
  • Bodyweight squats & lunges

🔵 Cool-Down (5–10 Minutes After Every Workout)

A cool-down reduces soreness & improves flexibility.

✔️ Light stretching for 30+ seconds per muscle group (hamstrings, quads, chest, shoulders).

✔️ Deep breathing exercises to lower heart rate.


3. Understanding RPE (Rate of Perceived Exertion) for Intensity Control

RPE is a self-measured intensity scale (1–10) to help regulate effort:

RPE Level

Effort Level

Example

1-3

Very light

Warm-up, mobility work

4-6

Moderate

Light workout, technique-focused

7-8

Hard

Challenging but controlled (most training should be here)

9-10

Maximum

Near failure or full exertion


📌 How to Use RPE:

✔️ For Strength: Train at RPE 7-9 (heavy but controlled).

✔️ For Hypertrophy: Train at RPE 6-8 (enough to fatigue muscles).

✔️ For Endurance: Stay at RPE 4-6 (sustainable effort).

How to Measure Your RPE (Rate of Perceived Exertion)

RPE is a subjective but highly effective way to gauge workout intensity. To measure your RPE, focus on how many more reps you could realistically perform before failure. If you finish a set and feel like you could do 2 more reps, your RPE is around 8 (meaning you're working at about 80% of your max effort).

If you could barely complete the last rep and couldn’t do another, that’s an RPE 10 (max effort). A good way to fine-tune your RPE awareness is to mentally estimate your effort, then test yourself—for example, if you think you have 2 reps left but fail on the next rep, you likely underestimated your RPE. Over time, this practice improves your ability to self-regulate intensity, ensuring you're training hard enough for progress but not over-exerting unnecessarily

How to Measure Your RPE for Cardio & HIIT Workouts

When doing cardio or HIIT, RPE is based on breathing rate, heart rate, and perceived effort rather than counting reps. Here's how to gauge it:

  • RPE 1-3 (Very Light): You can breathe normally and hold a full conversation easily (e.g., walking).
  • RPE 4-6 (Moderate): Breathing is slightly harder, but you can still talk in short sentences (e.g., jogging or moderate cycling).
  • RPE 7-8 (Hard): You're breathing heavily, speaking is difficult, and muscles are burning (e.g., sprint intervals, HIIT circuits).
  • RPE 9-10 (Max Effort): Near exhaustion—you can only sustain this for a few seconds, talking is almost impossible (e.g., all-out sprint, max-effort burpees).

📌 How to Use RPE in Cardio Workouts:

✔ Steady-State Cardio (Fat Loss & Endurance) → Stay at RPE 5-7 for sustainable effort.

✔ HIIT Workouts (Fat Burn & Conditioning) → Work intervals should hit RPE 8-10, with rest phases at RPE 3-5.

By listening to your breathing and perceived exertion, you can adjust intensity without needing heart rate monitors or other devices!


4. Action Steps for Today

✅ Practice foundational exercises in front of a mirror or with a friend.

✅ Arrive on time to class workouts & always warm up (5–10 minutes of light cardio & dynamic stretching).

✅ Test your RPE awareness by rating your intensity during each exercise.


Final Takeaway

Proper form is non-negotiable for long-term progress. Combine good technique, warm-ups, stretching, and RPE control to maximize results while staying injury-free!
