If you want to build your stamina at home, go for some weight exercises and strengthen your core. Use dumbbells for weight exercises. Exercises to boost stamina have many health benefits- including improving your lung capacity and heart health. For strengthening your core, go for pushups and planking. Try to progress to side planking eventually. If you have a stability ball, use it for rollout exercises to strengthen your core. Post-workout, go for a protein shake with Naturaltein whey protein powder to ensure maximum benefits.
