Short answer: https://bretcontreras.com/individual-differences-important-consideration-fitness-results-science-doesnt-tell/ Slightly longer answer - you should start to see strength gains right away. I've seen drastic results in as little as 5-6 weeks, and as long as 4-6 months - it just depends on how you respond to training, what stage you're at, and how well you've dialed in your nutrition. If you focus on rep ranges of 5-10, you'll also likely see fat loss so long as you're not overeating. Make sure to eat at least 1g of protein per lb of bodyweight to help with recovery and muscle building. Take girth measurements every week - take photos once a month. Go slow, have fun, and reap the rewards.
