🏋🏽 Exploratory Data Analysis: Gym Exercises

This repository contains an exploratory data analysis of gym exercises using Python.

Table of content

Introduction

This data analysis project focuses on exploring data from a csv dataset using Python.

The goal of this work is to explore and analyze the dataset to obtain valuable information about gym workouts.

The analysis process covers key steps such as data loading, data cleaning, data exploration, data analysis and data visualization using Python.

Goal

The ultimate goal of this project is to explore the csv file dataset to obtain all relevant information about a large collection of gym exercises.

Once the data is loaded, it will be cleaned and preprocessed to undergo univariate and bivariate exploration to then display and visualize the significant results obtained.

Through the exploration and analysis of the data, it is expected to find answers to the following points:

  • Most trained muscle groups
  • Most frequently used equipment
  • Most performed type of exercise
  • Most frequent type of user: beginner, intermediate, or expert
  • Most used muscle group and equipment in the different exercise types
  • User segmentation

Project overview

  1. Data loading
  2. Data cleaning: prepare the dataset for further exploration
  3. Data exploration:
    • Univariate analysis
    • Bivariate analysis
  4. Data visualization of the information obtained during the exploration
  5. Insights

Dependencies

The following tools are necessary to carry out this project:

  • Python 3
  • Jupyter Notebooks
  • Python libraries:
    • Numpy
    • Pandas
    • Matplotlib.pyplot
    • Seaborn

Technical skills

The following skills were used throughout the implementation of this project:

  • Data loading
  • Data cleaning
  • Data exploration
  • Data visualization

Data set

The data for this analysis is loaded from a csv file which can be found uploaded in this repository.

The dataset consists of:

  • 2918 entries
  • 9 columns

Data cleaning

Once the dataset was loaded, it was required to clean it to ensure its readability, comprehensibility, integrity and reliability.

For this purpose, column names were modified to make them more informative and improve readability, and missing values, duplicates and outliers were properly handled.

Data exploration

To obtain useful information from this dataset, an in-depth exploratory analysis was carried out. The dataset was analyzed in a univariate and bivariate basis.

Univariate analysis involved analyzing each variable in the dataset separately.

The bivariate analysis consisted of examining two different variables to determine whether there is a dependence or relationship between them.

Data visualization

Data visualization plays a crucial role in data analysis, as it is the stage at which the conclusions drawn from the analysis are effectively communicated.

This stage focuses on creating visual representations of the insights gained during the analysis. The Python libraries Matplotlib and Seaborn were used for this purpose.

Insights

The project successfully analyzed a wide range of existing gym exercises.

As expected from this project, the following questions were answered:

Most trained muscle group

The muscle groups that are trained the most are: abdominals, quadriceps and shoulders.

Exercise distribution per muscle group

Most frequent type of user: beginner, intermediate, or experts

Intermediate level users have the widest amount of exercises available, followed by beginners.

Exercise distribution per difficulty level

Most performed type of exercise

Strength and stretching are the most popular type of exercises.

Exercise distribution per exercise type

Most frequently used equipment

Bodyweight (body only), dumbbells and barbells are the most used gym equipment.

Exercise distribution per equipment

Most efficient equipment

The most efficient equipments are bands and body only.

Equipment efficiency

The body part that used the most amount of equipment are the shoulders.

Most used muscle group and equipment in the different exercise types

These are the most trained muscle group and gym equipment per exercise type.

Exercise Type Muscle Group Equipment
Cardio Quadriceps Body only
Olympic weightlifting Quadriceps Barbell
Plyometrics Quadriceps Body only
Powerlifting Hamstrings Barbell
Strength Abdominals Body only
Stretching Hamstrings Body only
Strongman Quadriceps Other equipment

User segmentation

  • Beginners:

    • mainly perfom strenght exercises,
    • focus their training in: quads, chest and hamstrings, and
    • mostly use their own bodyweight and barbells.

  • Intermediate users:

    • mainly train strength,
    • target: abdominals, quadriceps and shoulders, and
    • mostly use their own bodyweight and dumbbels.

  • Experts:

    • focus on strength training,
    • their training targets mainly:quadriceps, abdominalss and lats, and
    • mostly use their own body weight and barbells.
