The Three Heads of the Deltoid
The shoulder (deltoid) muscle has three distinct heads, each requiring targeted training:
- Front delt (anterior): Faces forward; trained by pressing and front raises
- Side delt (lateral): Faces outward; trained by lateral raises; creates the "width" look
- Rear delt (posterior): Faces backward; trained by face pulls and reverse flyes; critical for posture
The Aznolt® Muscle Trainer – Adjustable Resistance Trainer for Home Gym is uniquely effective for shoulder training because it can apply resistance from any angle — essential for hitting all three heads effectively.
The Complete Home Shoulder Workout
1. Shoulder Press — 4 × 10
Anchor at low position. Hold handles at shoulder height, press overhead to full extension. Primary mass builder for the front and side delts. Keep core braced throughout.
2. Lateral Raise — 4 × 15
Anchor at low position. Arms at sides, raise handles out to shoulder height with slight elbow bend. Isolates the side delt for shoulder width. This is the most important exercise for a broad-shouldered look.
3. Front Raise — 3 × 12
Anchor at low position behind you. Raise one or both handles forward to shoulder height. Targets the front delt. Use lighter resistance than lateral raises.
4. Face Pull — 4 × 20
Anchor at face height. Pull handles to face with elbows high and wide, externally rotating at the top. The single most important exercise for rear delt development and shoulder health.
5. Upright Row — 3 × 12
Anchor at low position. Pull handles straight up along the body to chin height, elbows leading. Targets side delts and upper traps. Keep elbows above wrists throughout.
6. Arnold Press Variation — 3 × 10
Anchor at low position. Start with handles at chest, palms facing you. Press overhead while rotating palms forward. Hits all three delt heads in one movement.
Shoulder Health Tips
- Always warm up rotator cuff muscles before heavy pressing (face pulls and external rotations)
- Train rear delts with equal volume to front delts to prevent imbalances
- Avoid pressing behind the neck — it places excessive stress on the shoulder joint
- If you feel impingement, reduce resistance and focus on form before increasing load
