Final answer:
Strength training equipment typically includes items like free weights, but not cardiovascular machines which are designed to improve aerobic fitness, not muscular strength.
Step-by-step explanation:
Types of equipment designed to improve one's strength include free weights, resistance machines, and hydraulic systems, but not cardiovascular machines like treadmills. Cardiovascular exercises focus more on improving heart health and aerobic endurance, not muscular strength directly. To enhance muscular strength, one should engage in exercises that require the muscles to exert force in a resistance-based manner, such as lifting weights or using resistance bands.
