  1. I agree we don’t have to go to the gym just to lose weight. Good entaig habit is enough. Do not eat to much. Discipline yourself play badminton with neighbors. drink plenty of water.

    • Its all about individual goals & finding the modality what works for each person. Training for fitness, performance or health should be targeted individually. Be active & eat clean for boost your health
