If you're a polished exerciser (this is Male oriented), I have developed a new Program which is arguably better than anything out, if you've got the where-with-all to go through with it. It's not for beginners, and it's not for anyone who doesn't take it mildly serious. It's a 4-day/week program. This program was developed to eliminate the need for weights AND cardio although, admittedly, I still do both because I'm slightly obsessed afterall. It's 48-exercises, split into 4-days. Each day has 4-rounds. Each round has 3-exercises, and 4-sets of each. Weight-wise, you want a pretty heavy weight where your MAX Reps are somewhere around 6. What you do in each round, is the 3-exercises right in a row (no rest), then go right back to the 1st (still no rest)..........and do this 4-times thus ending the round. So you might do something like squats.......right to curls.....right to dips.......back to squats.......etc. X4, /end round. 4 rounds per day, so 12 exercises per day. In the middle of the rounds, your heart is like . This routine builds muscle, but it's lean-muscle. Results come FAST. ~ The routine is on an excel-sheet. Anyone who-so desires, let me know. Not for beginners!!!(warning! warning!).
