About this routine

You don’t need a full gym to build impressive muscle. With a solid barbell, a pair of dumbbells, and the right structure, you can make serious progress right from home. This program is designed for intermediate lifters who already have some experience with resistance training and want a simple but effective way to keep gaining size and strength.

You’ll train four days per week using an upper/lower split. This setup lets you hit every major muscle group with enough intensity while still giving your body the recovery time it needs to grow. Each workout focuses on big, effective movements that deliver maximum results with minimal equipment.

Stick to controlled reps and good form on every lift. Rest around 60–90 seconds between most sets. If you’re pushing heavier compound movements, it’s okay to stretch that rest slightly so you can attack the next set with full effort.

For nutrition, prioritize protein at every meal to support muscle repair and growth. Lean meats, eggs, dairy, protein shakes, legumes, and whole foods should be your foundation. Stay well hydrated throughout the day and include plenty of fruits and vegetables to keep recovery and performance high.

If you use supplements, a basic stack works great with this program: whey protein after training to help recovery, creatine monohydrate daily for strength and performance, and a simple multivitamin to cover nutritional gaps.

Stay consistent for the full 9 weeks. Most people start noticing strength improvements and early physique changes around weeks 4–6. Keep pushing your weights up when possible, focus on clean reps, and let the progress compound week after week.
