What are the best workouts for those over 180 lbs?

I started at 215 doing bootcamp 3x pw... essentially a lot of HIIT, conditioning etc. It was hard and sucked... I complained - a lot. It gets better... I was not able to run around our building (.25 mile) at all when we started, I would walk it or elect to hold a plank while others ran. I've been at it a year and I ran it 4x this morning. I would just do what I could do and try to challenge myself a little each time. For example, one day I decided instead of doing all my pushups on my knees, I would try to do at least the first one on my toes... and it goes from there. I'm losing pounds (35tlt) and inches and I can see my body changing shape - I actually have muscles.
I do very little cardio (while I used to live on the elyptical) and focus on strength and conditioning.
Don't let your mind overrule your body. Do you belong to a gym that offers any fitness/conditioning classes ... maybe some Les Mills classes?

Weight loss is primarily diet. Eat at the appropriate calorie deficit and you will lose weight.

That said, exercise is a great addition. There are obvious benefits to your heart and overall health. But exercise will also get you a few extra calories to eat to make the transition to a lower calorie intake easier. I also love how empowered and strong I'm starting to feel. Lastly, it really gives you a better idea of the cost of every calorie you consume.

On to your other questions about exercise.
I started this life change at 240 lbs, the heaviest I've ever been. I started with walking. Sometimes 15 minutes per day. What helped was knowing that every little bit adds up. You don't need to do an hour straight. You can do 10 here, 15 there, etc etc. When the weather got nicer, I added in recreational swimming. Then tried a little running. They played more with my kids. It gets easier as the weight goes down, but it also gets easier as you get more accustomed to it.

Invest in good shoes. Cut yourself some slack. Push, without pushing too hard. It will all come in time. Set a goal to do something a little harder, a little longer, a little heavier each week. Even if baby increments. Find what you like. Try a class, explore the mountains, etc.

The best workouts are the ones that you enjoy, give you the results you want, and are sustainable over the long term. These will vary depending on your physical condition and your personal likes/dislikes.

Try attending some beginner-level classes of different activities that appeal to you. For outdoor sports, see if you can borrow or rent the necessary equipment so that you can try out the sport short-term without making a commitment. You are bound to find at least one thing that you really like!

Walking is one of the easiest, cheapest and most accessible exercises. All you need is a pair of good shoes and you're on your way. Whatever exercise you decide on, you;'re off to a great start and I wish you all the best

i'm that weight now - I started out a little higher. I dance (and can do this for hours on end), I lift weights, I swim, I walk, I do 30 Day Shred, I go to pilates.

I "can't" run - cos I hate it and the desire to stop totally overwhelms any motivation I had to do it in the first place - but other than that I don't think there is anything I can't do.

Start off doing something you enjoy - build it up so you are going for longer / going faster / going heavier over time. You don't have to start of running a marathon (or in my case - running at all!). As you get fitter from doing that try out some new things - but most importantly get started with something, and enjoy the ride!

Unless you have a reoccurring injury...the same ones that are best for those under 180 pounds.
