Begin with a warm-up that includes dynamic stretching and mobility exercises for the deadlift, pull-up, and push-up muscles. For deadlifts, use a weight that allows for good form and technique throughout the set. If 265/200 lbs is too heavy, reduce the weight to maintain proper form and safety. In pull-ups, aim for a full range of motion and use a band or jumping pull-ups if necessary. For push-ups, maintain a straight line from head to heels and focus on a controlled descent and explosive push-up. This circuit is designed to challenge your strength and endurance. Focus on maintaining good form and technique throughout the 30 minutes, and adjust the weight or reps as needed to maintain the workout's stimulus. Finish with a cooldown that includes stretching for the back, shoulders, and chest muscles.
