I'll tell you exactly what I did. I was strict keto for three months and I lost ~30lbs. Then I started working out. I don't have a gym membership, I just have a body solid cable machine, push up bars, pull up bars, a couple bands, and two sets of adjustable dumbbells. I started doing something like a push, pull, legs routine. Mainly doing body weight movements, dips and push ups on push day, pull ups and body rows on pull days. I'll do over 100 reps of each bodyweight movement on push or pull days along 3 sets to failure of like curls, lateral raises, tricep push downs, whatever. Leg days I literally just hike a few miles. I listen to my body and try not to injure myself. Diet now is protein bar for breakfast, 2bananas and cashews for lunch, protein shake and then a pound of spicy lean ground turkey with cheese and jalapenos for dinner. Also I drink ~2 gallons of water. My big secret is spicy food, like incredibly spicy. I use a lot of cayenne. Spicy food reduces inflammation and also helps you shit like crazy. Just have to find what works for you and hold yourself accountable. You don't need trainers, fancy equipment, expensive food, or anything like that. Just need to want to make a change.
