Push hard. Pull strong. Keep showing up.

From sled pushes to the SkiErg, this circuit challenges strength, endurance, and your ability to keep moving when the work gets tough. Different stations, one goal: build fitness that carries beyond the studio.

Choose a pace you can sustain, focus on quality movement, and let the team energy fuel your next rep. You bring the effort—we bring the coaching and encouragement.

One arm. Whole-body effort.

Taking a dumbbell overhead challenges more than your shoulders. Your core works to keep you steady, while your upper body controls the weight—making single-arm training a powerful reminder that strength and stability go together.

Keep your core engaged, avoid leaning back, and choose a weight you can control. Quality movement comes first; heavier weights can follow.

Raise the bar—and the dumbbell—with us at F45 Diamond Bar.

Different stations. Shared determination.

From BOSU crunches to kettlebell marches, this crew is putting core strength to work. Crunches challenge your abs, while loaded marches ask your core to keep you steady as you move—because strength is about more than lifting weight. It’s about controlling it.

Focus on smooth reps, steady breathing, and a pace you can own. Our coaches help you find the right challenge, and your teammates bring the motivation.

Show up. Find your station. Get stronger together at F45 Diamond Bar.

A little assistance. A lot of strength.

Band-assisted chin-ups build your back, biceps, and grip while challenging your whole body to work together. The band supports the movement—you still bring the effort.

Our fascia-focused cue: think re-tensioning. Connect your grip, shoulders, and core before the pull, then lower with control. Every rep is a chance to build strength through coordinated movement, not momentum.

Working toward your first unassisted chin-up? Let’s build it together at F45 Diamond Bar.
