Has anyone else used exercise especially in the gym to design a work out program for weight loss?
If your focus is weight loss, I would just focus on core exercises and maximum repetitions followed by 2 or 3 isolation exercises. Don't overdo it, maybe 3-5 sets per exercise with shorter rest intervals of 1 minute to a minute 45 (depending on if you're doing a compound movement like a bench, squat, or deadlift, or an isolation movement like a bicep curl).
Then, hit the treadmill for 30 minutes to an hour with a brisk walk, with an incline if you can, until you can get to a run.
But, the most important of all, is diet. You need to understand CICO: Calories In, Calories Out. For as long as you're eating more than you're expending in the gym, you're never going to lose weight like you want. Sleep would be secondary to that.
I would put diet and then sleep above exercise to lose weight. With the proper diet and sleep, your hormones will become more balanced, and you'll have a better effect when you do hit the gym.
Just try to get to the gym consistently. Consistency in all areas of diet, sleep, and exercise is the ultimate key to success.
On your off days, make sure you're taking 5000-10000 steps per day (use your cellphone or buy a cheap pedometer to keep track).
