Stabilization endurance. Resistance exercises should be done with lighter weight, higher reps, but very slowly, like a count of four on concentric (up) and count of four on eccentric (down) movements, with focus on form, neutral spine, core engagement. No step? Do reverse lunges.
We love these adjustable dumbbells from Rep Fitness. They take up very little space and are also very durable compared to other adjustable dumbbells on the market.
