Train every major muscle group with two focused working sets, guided rest-pause timing, and clear progression—all in 35 minutes or less.
Heavy Duty 35 is a focused resistance-training planner and timer built around complete full-body sessions that finish in 35 minutes.
Every workout covers seven movement groups: quads and glutes, hamstrings and glutes, chest and triceps, back and biceps, shoulders and upper back, calves, and core.
THE TWO-SET METHOD
• Set 1: Train with a moderate-heavy load and stop with 2–3 reps in reserve.
• Rest 30 seconds.
• Set 2: Perform clean reps to technical failure.
• Rest 10 seconds, then complete 1–3 final rest-pause reps.
• Transition to the next muscle group.
BUILT FOR FOCUSED TRAINING
• Design your session around gym, home, or minimal equipment.
• See full-body coverage before you begin.
• See a recommended number of easy ramp-up sets for every exercise.
• Follow every set, rest period, and transition with the guided timer.
• Log reps, load, RIR, duration, and productive training volume.
• Receive a simple next-session load or rep recommendation.
• Review cumulative progress by workout and muscle group.
PRIVATE BY DESIGN
No account, advertisements, analytics, or tracking. Your workout history and optional bodyweight stay on your device.
Heavy Duty 35 provides workout planning and logging, not medical advice. Technical failure means stopping when another repetition would require broken form. Use appropriate exercises and loads, and stop if you experience pain, dizziness, or unusual symptoms.
