Unlike the lateral raise, which trains shoulder abduction, the front raise moves the humerus forward in the sagittal plane — the exact mechanical action of the anterior deltoid. Both grip orientation and range of motion significantly affect activation distribution, with the pronated grip producing the highest anterior deltoid values. ## Execution 1. Stand with dumbbells in front of the thighs, pronated grip (thumbs toward each other) 2. Raise one or both arms directly forward to shoulder height (90°) with a slight elbow bend 3. Do not swing or use leg drive — keep the core braced and torso stationary 4. Lower under control without letting the weights drop through the eccentric ## What the EMG Data Shows **Grip comparison** (Demirtas 2023, n=14, 80% 1RM, concentric phase): | Grip | Anterior Delt | Notes | |------|--------------|-------| | Pronated (overhand) | 51.57% | Highest anterior delt in concentric | | Supinated (underhand) | 47.00% | Moderate | | Neutral/Hammer | 43.36% | Lowest anterior | **Full-rep comparison** (Sweeney 2014, n=16, 70% 1RM, pronated): | Muscle | Activation | |--------|-----------| | Anterior deltoid | 57.0 ± 11.9% | | Lateral deltoid | 36.0 ± 15.5% | | Posterior deltoid | 9.0 ± 5.8% | ## Programming Note The anterior deltoid receives substantial stimulus from all pressing movements (overhead press, incline bench, bench press). In most programs, the front raise adds redundant volume. Include front raises only when anterior delt is deliberately undertrained relative to lateral and posterior heads. ## Variations | Variation | Key difference | Best for | |-----------|----------------|----------| | Front cable raise | Constant tension at bottom of range | Lengthened anterior delt load | | Plate front raise | Fixed pronated grip; heavier load | Load progression | | Alternating front raise | Unilateral; core anti-rotation demand | Core integration | > For system-specific training applications, see each system's lens entry.
