To activate the hindquarters more and engage the forehand, riders can focus on exercises that encourage the horse to engage their hind end and lift their back. This can be achieved through exercises such as transitions, circles, lateral work, and hill work. By encouraging the horse to engage their hindquarters and lift their back, the weight distribution will naturally shift towards the forehand, activating the muscles in the forehand and encouraging the horse to work more through their whole body. Consistent training and correct riding techniques are key to developing a horse's strength and balance to achieve this. **
