Hello dear Visit your physiotherapist before you start gym.

Extension exercises x 15 times x twice daily. Bhujang asana. Core strengthening exercises. Back stretching stretch. Do the cat/cow avoid bending in front. Postural correction- sit tall, walk tall. Apply hot fomentation.

Let's consider your ""slip disc "". Please go for a fresh evaluation. Find out has it progressed or is it the same. Hope you were advised physio and we're able to consult and efficient physio. If not go NOW get therapeutic exercise. Age is in your favour. Please make use of it. ""Going to the gym"" please understand this you going to gym and loosing weight have no connection with each other. Please focus on fitness . Being happy. Do take a relook at what you are eating and practice portion control. If you do choose to exercise please do so to be fit not to loose weight. Being happy is the best medicine.

You must consult a good physiotherapist nearby before starting any exercises. Focus on building back and abdominal muscles that is  Core Muscles first. Swimming is better than gymming to start with.
