Treadmill hackMost people aren’t aware of the right way to walk on a treadmill. Devin recommends walking on the incline mode at 11 or 12 for 30 minutes on the treadmill. You can keep the speed at 3 to 3.5 mph and maintain this frequency for up to 4 to 5 days a week. It burns 300 to 400 calories of pure fat, doesn’t spike cortisol, doesn’t make you hungry, and also doesn’t hurt your joints.2. Stretch your rest periods to 90 secondsMost people rest 30 to 45 seconds between sets and wonder why they can't lift heavier. Devin highlights that 90 seconds lets your nervous system recover, your breathing reset, and your muscles ready for the next set. You'll lift 10 to 20% more weight per set. You'll progress every week instead of stalling at the same numbers. The clock is your friend. Use it.3. Do your first set as your heaviest setMost people pyramid up and move from light to heavy. But Devin advises reversing the same. He recommends starting with the heaviest set first when you're fresh and then dropping weight from there. This will help you lift more total weight, build more muscle, and burn more calories every session.4. Track your top set every workoutMost people walk into the gym and see how they feel, and that's why they look the same after 3 years. According to Devin, open the notes app on your phone and write down exercise, weight, reps, and sets. Beat last week by 5lbs or 1 rep in every single workout.5. Train for three to four days, not sixMost overweight beginners overtrain and quit by week six. However, you should try training three days a week. You can do 45 minutes per session and full rest days in between.Day 1: Upper bodyDay 2: Lower bodyDay 3: Full bodyDay 4: Optional (Push or Pull)6. Eat 30g of protein 60 minutes before liftingNutrition is equally important. According to Devin, pre-workout meals actually move the needle. You can consume one scoop of whey + half a cup of Greek yoghurt + half a banana. This equates to 30g of protein and 250 calories.7. Squeeze the muscle at the top of every repMost people lift weights, and lean people contract muscles. There's a difference. Here’s how you should do:Bicep curl: squeeze the bicep at the top for 1 secondLat pulldown: squeeze the back at the bottomBench press: squeeze the chest at the topThis single change doubles the time under tension and triples the muscle growth from the same workout.8. Wear a 20lb weighted vest on your daily walksDaily walking burns 200 calories, and daily walking with a 20lb vest burns 350 calories. Adding 20lb helps in burning 75% more calories. You're also building bone density, core strength, and posture without a single extra workout. This is one of the most underrated fat loss accessories you can buy.Note to readers: This article is for informational purposes only and not a substitute for professional medical advice.
