Hey welcom aboard. Since you're new to the gym, start with a structured routine focusing on progressive overload. A good plan is training 3–4 times a week with key compound lifts like squats, deadlifts, bench press, pull-ups, overhead press, and some arm work. Aim for 8-12 reps on most exercises and gradually increase weights over time.
Eat in a slight calorie surplus with plenty of protein (2g/kg per day), carbs for energy (rice, oats, potatoes, fruits), and healthy fats (nuts, olive oil, avocado). Reduce/elimate alchol and NSAIDs. Drink plenty of water (3L min) and make sure you’re eating enough to fuel growth. Guessing from your weight and taking average height you're not eating enough.
Supplements aren’t necessary, but whey protein can help you meet your protein goals easily, creatine (5g daily) can support muscle growth and strength, and fish oil and magnesium can aid recovery.
Get 7-9 hours of sleep, take rest days when needed, and track progress by monitoring weight, strength, and monthly progress photos. I recommend an app like Hevy. Stay consistent, be patient, and you’ll see results.
