I want to lose weight I'm 5'7" and weigh 194lbs. My goal is to get to the 150ish mark.
Hopefully you realize diet is going to be the primary driver that gets you to that goal, right? That said, what's your calories and food selection look like on a typical day.
My question is how long would it take to get down to my target goal, and how long would it take before I would start to see results?
1. I wouldn't worry about how long it will take to start seeing results. This is a slow process and the sooner you align your expectations with that, the better off you'll be.
2. If you want a plan for monitoring progress, assessing things once every 2-4 weeks is a good idea. By that, I mean take anthropometric measurements, weigh yourself, take pictures, etc. Based on the trends of your assessments, you can adjust your diet and training accordingly.
3. A decent rate of weight loss, on average (some weeks will be more, some less) is 1% of total bodyweight lost per week. It's not a law, but it's a good thing to adhere to.
I plan to use a combination of this weight lifting routine: with a HIIT bike session on the alternating days.
Have you exercised with weights before? Specifically, have you done the exercises listed in that program? The reason I ask is I've been working in this industry professionally for near a decade and I can count on my fingers how many people I've seen do proper deadlifts and squats without a quality trainer instructing them.
Also, why are you jumping right into HIIT? Do you have an aerobic base of fitness established already?
And if so, I wouldn't be alternating HIIT with strength training. When dieting, recovery ability is diminished. Knowing this, it makes a whole lot of sense to insert as much recovery into your programming as possible. This is accomplished, assuming we're talking equivalent work loads/volumes, by consolidating high intensity sessions.
HIIT and strength training are both considered high intensity as they demand a lot of output in terms of the central nervous system.
So instead of something like:
Day 1: Strength
Day 2: HIIT
Day 3: Strength
Day 4: HIIT
Day 5: Strength
Day 6: HIIT
Day 7: Off
I'd much sooner see something like:
Day 1: Strength + HIIT
Day 2: LISS or off
Day 3: Strength + HIIT
Day 4: LISS or off
Day 5: Strength + HIIT
Day 6: LISS or off
Day 7: off
That would insert a lot more recovery days into the week. And that's assuming you *should be* doing all that high intensity work to begin with. More often than not, I'll work in two sessions of HIIT per week and 2-3 sessions of strength training per week with someone with similar goals as your own. The leaner they get and the longer they've been at it, the more likely I am to drop high intensity cardio all together due to the recovery ability mentioned above.
