Starting to exercise is the best decision you can make for your health. But the amount of contradictory information online is paralyzing. This guide gives you a concrete plan for your first week, no complications.

Rule number 1: less is more

The most common beginner mistake is doing too much too soon. Start with 3 days per week, never 2 consecutive days.

  • Monday: Upper body (chest, back, shoulders, arms)
  • Wednesday: Lower body (quads, hamstrings, glutes, calves)
  • Friday: Full body (one exercise per muscle group)

Fundamental exercises

  • Chest: push-ups or bench press
  • Back: dumbbell row or assisted pull-ups
  • Shoulders: military press or lateral raises
  • Legs: squats (the king of exercises)
  • Core: front plank 30-60 seconds

Sets, reps and rest

  • 3 sets of 10-12 reps per exercise
  • 60-90 seconds rest between sets
  • Weight: the last 2-3 reps should be challenging but with good form
  • Total duration: 40-50 minutes
  • Warm-up: 5-10 min light cardio + joint mobility

Beginner mistakes to avoid

  • Not warming up (high injury risk)
  • Lifting too much weight with bad form
  • Not resting (muscles grow when you rest)
  • Comparing yourself to others
  • Only doing abs (abs are made in the kitchen)
