@kimerella2 Hey. When I was 140-50lbs, I did full body weight routine 3 times a week with focus on high reps and keeping heart rate up, followed by 20-30mins of cardio at the end (or during), and then did cardio (stepper) 2-3 times a week on my rest days. I also did a mix of yoga and hot yoga a couple of times a week at that point but I'm not sure that had much impact ha. I followed a super low carb (think swapping out rice and making cauliflower rice instead, bleugh) and high protein diet in a deficit of around what you're on now. A PT advised me these calories, but it was only for a short period of time of around 8-12 weeks (I cannot remember the exact time it took). My focus here wasn't actually to build muscle, but lose weight and recomp, so getting sweaty through intense cardio was a huge factor.
I then increased my calories to around 1,500 over a period of weeks, before the pandemic hit and everything went into shut down. I started back at the gym properly in March this year, with a new PT and a more challenging routine where I am focused on increasing weights (rather than just focusing on high reps and low weights) so my calories first went up to 1,750 (4 x week) and they are now sat at 2,000 (4-5 x week). My goal today is building muscle, so I will be increasing this number soon (bulk).
I know a lot of people try to do both at the same time (losing fat and building muscle) and this mindset is great (more sustainable and more mentally healthy) but it is a lot slower than focusing on one primary goal of losing weight or building muscle. As far as based on my experience anyway. I think if I was restarting this journey I would go slow and healthy over fast and furious.
How do you feel day to day on 1,350? Are you eating the right kinds of foods to nourish yourself well and give yourself enough energy? Honestly, I would advise getting a PT if you can. This is how I've seen the best results in the quickest time. Sorry that's not much help lol.
Edit: Because you're quite close to your goal weight anyway, it's gonna be a slower process to shed off that final stone. It deffo got more challenging for me the closer I got to 110lbs (my fasted weight now fluctuates between 106-110 depending on hormones, 107 wasn't really a goal or anything). Patience is key
