What are the essentials for at home.?.weights ball resistance band ect. Where to start?

To echo @ashliefisch, the most important thing is going to be your diet. You can't out run a bad one. To make that happen effectively, you really NEED a digital food scale and then weigh everything you eat. I say weigh because measuring by volume can be subjective. The scale is not subjective, it is going to give you the precise reading.

Next you need to get a good baseline of where you are: weight, height, measurements, body fat percentage and a pic of you in something that can't hide where you are. Be modest so you can show others though If you plan on lifting, then a baseline of what you are capable of. Here are some great Day 1 body weight exercises: push up, lunge, squat and crunch. See how many perfect one you can do. All of these will give you points of comparison 30, 60, 90, 365 days down the line.

Lastly, pick short term and long term goals. Don't just say you want to lose 50 lbs or be able to run a 5k. That may well be you "end" goal. Instead set your goals to maybe 10 lbs in six weeks or be able to walk a 5k. As you reach your goals, celebrate the accomplishment and set new goals. No one climbed Everest in a day. Effort and perseverance off the field make winners on the field.

Welcome to MFP. Good Luck!

OP, I have an elliptical/stationary bike and use them 90% of the time. I also walk or run every day. I did not start running until I was on maintenance, but used the elliptical/bike every day until then and walked 3 miles per day. I lost 75# this way. Oh, yeah, MFP had me on 1200 calories. Made me very crabby. I suggest eating more calories and exercising. My best advice is to start out slow so you do not burn out or injure yourself. At first, I could only do 5 minutes elliptical/15 bike. I worked up the times to an hour and finally an hour just elliptical. You may friend me if you want. Best wishes
