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)

3-day full-body routine — week 1 to 4

Here is the exact 3-day full-body template most strength coaches use for the first month. Three exercises per session cover the four major movement patterns (squat, hinge, push, pull), plus core. Sets and reps are tuned for technique acquisition, not maximal strength yet:

MonSquatBench pressRowPlank3 x 8-10
WedDeadliftOverhead pressPull-downHanging knee raise3 x 6-8
FriFront squatIncline pressCable rowSide plank3 x 10-12

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)

Renzy will not write your routine, but it covers the half beginners neglect: photograph each meal and you get calories, macros and whether you reach the protein a new lifter needs. Your sessions come in from Apple Health or Health Connect with the calories burned, and the weight trend shows over the weeks whether the plan is moving you.
