Writing down any words or expression out of my head and speak. It's actually helpful cuz it makes me bring them back to my memory and use in my spoken English. I've been dealing with vocabulary issues when I speak. A method found for myself. Plus rather than grabbing barbell in the gym I moved to the rooftop for general atheletism training like hopping, jumping so on.. It's pretty good for developing atheletism and refreshing myself from same training. (just weightlifting movements with barbell mostly)
