For outbound traffic:


Configure an IGP between the routers and the LAN, and let the IGP take care of load balancing.


Configure two HSRP and user groups.

Configure Router1 as active HSRP for group1 and Router2 as active for group2.

For inbound traffic, it depends on how your two Internet circuits are set you have BGP session w/ the ISP?

If you do, you can ask the ISP to do multi-path, or, you can advertise half of your prefixes through one link w/ higher preference (not local pref, but other means of manipulation such as prepend), and the other half through the other link.
