Functional exercises are a great way to improve your asthma, but don't forget to warm up and cool down before and after each session. Squats are a basic functional movement that work on lower body strength and mobility. You can adjust the depth and width of your stance, or try variations like goblet squats, sumo squats, or split squats to target different muscles and challenge your balance. Lunges are another functional movement that work on lower body strength and stability. You can change the direction and distance of your step for different levels of difficulty, or try variations like reverse lunges, lateral lunges, or curtsy lunges to work on different planes of motion and challenge your coordination. Push-ups are a functional movement that work on upper body and core strength. You can adjust the position and width of your hands to suit your comfort level, or do variations like incline push-ups, decline push-ups, or diamond push-ups to target different muscles and challenge your intensity level. Rows are a functional movement that work on upper back and arm strength. You can use dumbbells, kettlebells, resistance bands, or a cable machine to adjust the weight and speed to suit your ability level. You can also try variations like single-arm rows, bent-over rows, or renegade rows to work on different muscles and challenge your stability. Planks are a functional movement that work on core and overall stability. Adjust the duration and position to suit your comfort level, or do variations like side planks, plank with leg raises, or plank with arm reaches to target different muscles and challenge your balance.
